The FESTO LC-3-1/8, part number 3737, is a basic valve body designed for pneumatic control applications that require compact structure, simple installation, and dependable airflow handling in industrial automation systems. According to Festo’s official datasheet, this model is identified as LC-3-1/8 with part number 3737, a standard nominal flow rate of 80 l/min, a working pressure range of 0 to 8 bar, and a pneumatic connection at port 1 of G1/8. Festo also marks this type as a product to be discontinued, noting that it was available until 2018 and that alternative products should be checked through the support portal.
For the product weight, the currently surfaced official Festo datasheet page does not display a weight line in the text that is accessible here. However, Festo-linked CAD metadata and industrial digital-twin listings for the exact same part number 3737 LC-3-1/8 show a net weight of 0.096 kg, which is 96 g. Because that value comes from CAD metadata rather than the visible line of the official one-page datasheet, it is best described as a CAD-listed product weight for this exact part number.

The values in this table are based on Festo’s official datasheet for part number 3737 together with Festo-linked CAD metadata for weight. The string “X502” in your request does not appear in the surfaced official model identification, so the article below is written against the identifiable official product designation FESTO LC-3-1/8, part number 3737.
Product Overview
The LC-3-1/8 belongs to an earlier generation of FESTO pneumatic valve components that were built around practical industrial requirements rather than digital communication features or highly integrated electronic control. Its product designation as a basic valve body is important. This means the LC-3-1/8 is not being positioned as a complete smart manifold or a modern fieldbus-enabled valve terminal. Instead, it is fundamentally a pneumatic valve body intended to serve as a functional core element within a compressed-air control arrangement.
This kind of component has value in many maintenance, retrofit, and legacy-equipment situations. In factories and process environments, many systems remain in operation long after their original product family has been discontinued. In those cases, the correct part is often more important than the newest part. A legacy FESTO valve body such as the LC-3-1/8 can still be highly relevant when a user is trying to maintain an installed machine, restore an older pneumatic station, or match an original design that was built around a specific airflow class and connection size. That relevance is reinforced by the fact that Festo explicitly flags this type as discontinued and points users to alternative products only through its support process, which usually indicates an installed-base service situation rather than an actively promoted current platform.
Functional Position in Pneumatic Systems
Although the surfaced official datasheet is brief, it still provides enough information to place the LC-3-1/8 in a meaningful application context. With a standard nominal flow rate of 80 l/min, the product sits in a compact pneumatic range suitable for low-to-moderate air-consumption tasks rather than high-flow actuator control. In practical terms, this makes it more appropriate for smaller pneumatic functions, signal-level air handling, compact actuator circuits, or machine sections where airflow demand is controlled and the footprint matters.
The 0 to 8 bar working pressure range is also significant. It places the valve body squarely within common industrial compressed-air practice. Many factory pneumatic systems operate comfortably inside that envelope, so the LC-3-1/8 was clearly designed for mainstream plant air rather than for unusual pressure classes. Its G1/8 port size supports that interpretation as well. G1/8 is a standard compact pneumatic connection size that is commonly used where tubing and components need to stay relatively small while still providing practical flow for localized machine functions.
Compact Size and Mechanical Value
The reported 96 g product weight is worth highlighting because it helps explain the physical class of the LC-3-1/8. A component under 100 g is clearly positioned as a compact pneumatic element rather than a heavy directional valve body for large cylinders. For designers and maintenance engineers, weight is not only a catalog number. It also indicates how easily a part can be mounted in tight spaces, integrated into compact assemblies, or carried as a spare for service work. In older machinery especially, small and lightweight pneumatic parts often make repair and replacement less disruptive because they can fit into restricted mechanical layouts without secondary bracket changes.
From a mechanical integration perspective, the LC-3-1/8 appears to have been designed for straightforward pneumatic use, with the official data exposing only the core values that matter most at selection stage: model, part number, flow, pressure, and connection. That kind of concise datasheet is typical of mature catalog pneumatic components where the product family was already well understood in the market. The lack of marketing-heavy feature expansion also suggests the part’s role was practical and utilitarian: provide a reliable valve body with known airflow and connection characteristics. This is partly an inference, but it is consistent with the structure and content of Festo’s official one-page datasheet for this item.
Product Lifecycle and Replacement Considerations
A critical commercial fact about the LC-3-1/8 is that FESTO classifies it as a product to be discontinued, with availability indicated only until 2018. That point should not be ignored. If a customer is sourcing this model today, the context is likely one of spare-parts replacement, legacy-machine repair, inventory liquidation, or second-hand/aftermarket maintenance supply rather than fresh OEM standardization for a new design.
That does not reduce the value of the part. In fact, for many industrial buyers, discontinued products are commercially important because they keep older production assets running. The real issue is not whether the LC-3-1/8 is old, but whether it is the correct match for the installed system. If the machine was originally built around this valve body, using the same model can reduce retrofit effort, preserve pneumatic performance consistency, and avoid unnecessary adaptation work. Festo’s own note directing users to alternative products through the support portal confirms that replacement planning is part of the product’s lifecycle reality.
Why This Model Still Matters
In search-engine terms and in real industrial procurement practice, products like the LC-3-1/8 still matter because users often search by exact model number, part number, and connection size when dealing with replacement parts. The combination LC-3-1/8, 3737, and G1/8 is therefore commercially important. Buyers looking for this product are usually not browsing casually. They are typically trying to identify a correct FESTO spare, match an existing valve body, or verify whether a stock item corresponds to a legacy machine requirement. That is why a clear product introduction remains useful even for a discontinued component.
The 80 l/min nominal flow also makes the LC-3-1/8 attractive for applications where oversized valves would be unnecessary. In compact automation, over-dimensioning pneumatic hardware can increase cost, consume space, and complicate maintenance. A smaller valve body with the correct connection and flow class is often the better engineering choice. The LC-3-1/8 fits that logic well. Its published values suggest a compact and focused pneumatic component intended for controlled airflow duties rather than large-scale actuation.
Typical Application Context
| Application Context | Why LC-3-1/8 Fits |
|---|---|
| Legacy machine maintenance | Exact part-number matching for older FESTO pneumatic systems |
| Spare-parts sourcing | Clear identification through model LC-3-1/8 and part number 3737 |
| Compact pneumatic circuits | G1/8 connection and 80 l/min nominal flow suit small air circuits |
| Retrofit support | Lightweight valve body may simplify mechanical replacement |
| Inventory verification | Discontinued status makes exact identification commercially important |
These application contexts are inferred from the official technical values and the explicit discontinued-product notice in Festo’s datasheet.
SEO and Commercial Description Value
For online visibility and catalog-style presentation, the LC-3-1/8 benefits from being described in plain industrial language: basic valve body, FESTO part number 3737, G1/8 connection, 80 l/min flow rate, 0 to 8 bar pressure range, and 96 g weight. These are the exact kinds of details engineers, buyers, and spare-parts managers look for when filtering results. Since this is not a consumer product, search relevance depends heavily on exact identifiers and usable technical data rather than promotional wording.
At the same time, honesty matters. The weight figure is supported by CAD-linked metadata for the exact FESTO part number, while the visible official one-page datasheet does not expose the weight line in the text retrieved here. That distinction is important for technical credibility, especially in industrial markets where buyers often compare multiple sources before ordering.
Conclusion
The FESTO LC-3-1/8, part number 3737, is a compact basic valve body intended for pneumatic applications that require a practical connection size, modest airflow capacity, and straightforward integration into existing air-control systems. Official Festo data confirms a standard nominal flow rate of 80 l/min, a working pressure range of 0 to 8 bar, and a G1/8 pneumatic connection at port 1. The product is officially marked as discontinued, with availability noted until 2018. Based on FESTO-linked CAD metadata for the exact same part number, the product weight is 0.096 kg, or 96 g. For legacy machine maintenance, spare-parts replacement, and exact-model procurement, the LC-3-1/8 remains a relevant and technically identifiable FESTO component.
