PASS Coupling Model 75L: Stainless Steel Grooved Coupling for Low-Pressure Piping Systems

When dependable grooved piping connection is required for low-pressure systems, the PASS Coupling Model 75L offers a practical and reliable solution. Designed as a stainless steel flexible grooved coupling, it helps connect prepared grooved pipe ends while supporting easier installation, corrosion resistance, and long-term piping performance.

For contractors, engineers, water treatment operators, and maintenance teams, choosing the right PASS Coupling Model 75L can help improve piping reliability, simplify maintenance, and support efficient pipe joining in water treatment, filtration, and utility piping applications.

What Is a PASS Coupling Model 75L?

The PASS Coupling Model 75L is a stainless steel low-pressure flexible coupling mainly designed for low-pressure grooved piping systems. Public product information lists the Model 75L for applications such as low-pressure microfiltration, ultrafiltration, reverse osmosis systems, municipal water piping systems, and grooved piping systems. It is listed with a rated working pressure of 350 psi / 25 bar, for cut groove only applications.

The PASS Coupling Model 75L is available in sizes from 3/4 inch to 12 inches, or DN20 to DN300, and is supplied in CF8 stainless steel / 304 or CF8M stainless steel / 316. It also uses 316 bolts and nuts, which support anti-corrosion performance and longer service life.

Key Benefits of PASS Coupling Model 75L

Reliable Grooved Pipe Connection

The PASS Coupling Model 75L is designed to connect compatible grooved pipe ends securely. Its mechanical coupling design helps provide a dependable connection for low-pressure piping systems where proper sealing, alignment, and serviceability are important.

Stainless Steel Construction

The PASS Coupling Model 75L is supplied in stainless steel material options such as CF8 and CF8M. This makes it suitable for piping systems where corrosion resistance is an important requirement, especially in water treatment and utility water applications.

Suitable for Low-Pressure Filtration and RO Systems

The PASS Coupling Model 75L is commonly associated with low-pressure microfiltration, ultrafiltration, and reverse osmosis systems. This makes it a practical coupling option for water treatment facilities and filtration piping layouts.

Flexible Coupling Design

As a flexible grooved coupling, the PASS Coupling Model 75L may help accommodate minor system movement, alignment tolerance, or vibration depending on the piping design and installation condition. Final suitability should always be checked based on the project specification and manufacturer’s installation requirements.

Easier Installation and Maintenance

Grooved couplings can help simplify pipe joining compared with welded or flanged methods. The PASS Coupling Model 75L supports easier installation, inspection, and maintenance when used with properly prepared grooved pipe ends and compatible gasket materials.

Why Choose a Stainless Steel Low-Pressure Grooved Coupling?

A stainless steel low-pressure grooved coupling is often selected when the piping system requires corrosion resistance, easier installation, and a serviceable mechanical pipe joint. The PASS Coupling Model 75L provides a practical solution for low-pressure water treatment, filtration, municipal water, and utility piping applications.

Compared with permanent welded connections, grooved couplings can help make future inspection, maintenance, and piping modification more convenient. For projects involving multiple pipe sections, filtration skids, or mechanical rooms, this can help support better installation planning and easier system servicing.
