The Suttner Screw Coupling 200040810 is a high-pressure ST-40 (B) screw coupling constructed from corrosion-resistant brass, built to handle up to 5800 PSI and temperatures of 300°F (149°C). Designed for compact equipment and light-to-heavy-duty pressure washer systems, it enables a secure transition from 1/4\\” MPT connections to M22 European-style threads.
This coupling is precision-machined from high-quality brass to ensure strength, leak resistance, and reliable long-term performance in chemically demanding and high-pressure environments. It is ideal for integrating spray guns, hoses, and lances across systems with mixed thread standards.
The ST-40 (B) model features a 1/4\\” Male NPT (MPT) inlet and an M22 outlet, making it ideal for smaller-diameter pressure washer systems that require M22 compatibility.

-
Compact and portable pressure washer systems
-
Spray guns and accessories with 1/4\\” NPT connections
-
Adapters for chemical sprayers and foamers
