Features & Key Specifications

Features & Key Specifications:

Multiple Stainless Steel Grades (304, 316, 316L):

Choose the right material for your budget and application. We offer 304SS for general-purpose corrosion resistance, 316SS for superior protection against chlorides and chemicals, and 316L for the most critical applications.

Comprehensive Size Range:

We stock a full range of sizes to fit any system. Tube ODs are available in metric (4, 6, 8, 10, 12, 14, 16mm) and inch (5/32", 1/4", 5/16", 3/8", 1/2"). Port Sizes include M5, 1/8", 1/4", 3/8", 1/2", and 3/4" in NPT, BSPP, and BSPT threads.

Food-Grade & Oil-Free Design:

These fittings are manufactured oil-free and are fully compliant with food hygiene standards, ensuring the safety and purity of your process.

High-Performance FKM O-Ring:

Equipped with an FKM (Viton) O-ring that offers excellent resistance to chemicals, steam, and a wide operating temperature range of -20°C to 140°C.

Versatile Media Compatibility:

Designed to reliably handle not just compressed air, but also water, steam, and various other liquids, making them a truly versatile process fitting.

Application Fields

The Professional Choice for Critical Connections:

Food & Beverage Industry: Perfect for pneumatic systems on processing, filling, and packaging machinery that undergo frequent washdowns.

Pharmaceutical & Medical: Used in cleanrooms, for medical device manufacturing, and in systems handling purified water or steam.

Chemical Processing: Providing durable, chemical-resistant connections for control air lines in corrosive environments.

High-Temperature Applications: Reliably handling connections in environments with steam or ambient temperatures up to 140°C.

Marine & Outdoor: Offering superior protection against saltwater and environmental corrosion.

Technical & Selection Guide

Choosing Your Stainless Steel Grade

304 Stainless Steel: The industry workhorse. An excellent and cost-effective choice for food processing, freshwater systems, and general industrial atmospheres.

316 Stainless Steel: The premium choice for superior performance. Highly resistant to chlorides (salt), acids, and harsh industrial chemicals. Essential for marine and chemical applications.

316L Stainless Steel: A low-carbon version of 316. The "L" stands for "Low Carbon," which further enhances its corrosion resistance, especially after welding. It is the top-tier choice for the most critical applications.

FAQ

Frequently Asked questions

Q: What type of tubing can be used with these fittings?

A: They are compatible with semi-rigid tubing such as Polyurethane (PU), Nylon (PA), and Polyethylene (PE). For high-temperature applications, FEP or PFA tubing is recommended.

Q: Can I really use these fittings for steam?

A: Yes. The combination of the stainless steel body and the FKM O-ring makes them suitable for low-pressure steam applications within the specified temperature range (-20°C to 140°C).

Q: What is the main difference between 304 and 316 stainless steel?

A: 316 stainless steel contains an element called molybdenum, which 304 does not have. This gives it significantly better resistance to corrosion, especially from salts and many acids.
