If you are working with stainless steel tubing, our compression fittings offer unmatched performance, reliability, and ease of installation.
What Are S-Series Compression Fittings?
S-Series Compression Fittings are mechanical fittings designed to create strong, leak-proof seals in metal tubing systems, particularly those utilizing stainless steel tubing.

Key Features of Portage Specialty’s S-Series:
At Portage Specialty, our S-Series Compression Fittings are manufactured to the highest industry standards. Here are the key features that set them apart:
1. Two-Ferrule Design for Maximum Sealing:
Our S-Series uses a twin-ferrule mechanism. The front ferrule provides a tight, pressure-resistant seal, while the back ferrule grips the tubing for added strength and vibration resistance. These are designed in seal of good material.
2. 316 Stainless Steel Construction:
These fittings are precision-machined from 316 stainless steel, known for its superior corrosion resistance and strength. This makes them ideal for harsh environments including offshore rigs, chemical processing plants, and pharmaceutical labs.
3. Wide Range of Sizes and Configurations:
We offer a broad selection of sizes (1/16” to 1”) and connection types, including unions, elbows, tees, reducers, and bulkhead fittings. Whether your system requires complex routing or simple in-line connections, we have a configuration that fits.
4. Interchangeability:
Portage Specialty’s S-Series fittings are designed to be dimensionally and functionally interchangeable with major fitting brands. This provides flexibility and peace of mind for maintenance and retrofitting operations.
Benefits of Using Compression Fittings for Stainless Steel Tubing:
Stainless steel tubing is a go-to choice for fluid and gas transport systems due to its high durability, corrosion resistance, and cleanability for long time with warrenty and other benefits in portage speciality. S-Series Compression Fittings is the best fittings, when paired with the right fitting like our S-Series.
Leak-Free Reliability:
The metal-to-metal seal created by S-Series fittings ensures long-term leak-free performance, a critical factor in systems handling toxic, flammable, or sensitive media in this no leakage problem
Easy Installation and Maintenance:
Unlike welded systems, S-Series Compression Fittings do not require specialized tools or welding expertise and it is made of pure material. Assembly and disassembly are quick and simple, which reduces system downtime and labor costs.
High Pressure and Temperature Resistance:
Stainless steel combined with our precision-engineered design makes these fittings capable of handling extreme conditions without deformation or failure.
Clean and Contamination-Free:
Compression fittings maintain the integrity of the tubing's inner diameter, minimizing turbulence and potential contamination. This is essential in industries such as pharmaceuticals and food processing where cleanliness is non-negotiable.
Common Applications:
Our S-Series Compression Fittings are trusted across a wide array of industries:
Oil and Gas: Used in instrumentation panels, hydraulic systems, and pressure regulators.
Chemical Processing: For high-purity chemical transport and sampling lines.
Pharmaceutical Manufacturing: Ensuring clean, contamination-free connections.
Power Generation: In high-pressure steam and water system.
