3″ Stainless Steel Pipe Coupling | 350PSI

Our 3″ Stainless Steel Pipe Coupling is engineered for high-performance sealing in commercial and industrial piping systems. Constructed with a 304 stainless steel housing, nuts, and bolts, this coupling delivers excellent corrosion resistance, mechanical strength, and long-term durability in demanding environments.

The coupling features a premium EPDM elastomer gasket, providing superior resistance to water, steam, ozone, and weathering. This ensures a reliable, leak-free seal across a wide range of operating conditions. With a maximum working pressure of 350 PSI, this coupling is ideal for high-pressure water filtration systems, RO equipment, and industrial fluid transfer applications.

Its split-body design allows for fast installation and easy maintenance without disassembling the piping system, reducing downtime and labor costs. Precision-machined components ensure uniform clamping force and consistent sealing performance.

Applications:

• Water filtration systems
• Reverse osmosis systems
• Commercial plumbing
• Industrial process piping
• HVAC systems
• Irrigation systems
• OEM equipment
• Municipal water systems
