The Suttner Screw Coupling 200040820 is a heavy-duty ST-40 (C) screw coupling made from durable brass, engineered for high-pressure applications up to 5800 PSI and 300°F (149°C). This coupling provides a secure transition from 3/8\\” FPT U.S. standard threads to M22 European-style connections in pressure washer systems.
Designed for high reliability, the ST-40 (C) coupling offers outstanding sealing and strength, thanks to its corrosion-resistant brass construction. It is an essential component for adapting spray guns, hoses, and accessories that use mixed thread types in both commercial and industrial environments.
This model features a 3/8\\” Female NPT (FPT) inlet and an M22 outlet, offering compatibility with standard male-threaded U.S. fittings and M22-threaded components commonly found in European systems.
Applications:
-
Industrial and commercial pressure washer systems
-
Hose-to-accessory and gun-to-lance transitions
-
Chemical and sanitation spraying equipment
-
Cross-compatibility with M22-threaded tools
