Test 20 Coupler, M16x1.5 Male Thread, Poppet Check Valve, FKM Type C Elastomeric Seal

Engineered for high-pressure performance and ease of use, this Test Coupler is part of the trusted Test 20 Series with M16x1.5 male thread and M16x2 test port connection. Designed for efficient system pressure monitoring, fluid sampling, and venting without tools or downtime, it’s a reliable choice for diagnostics and maintenance. The robust steel body houses a piston-style valve that only opens when connected to a test hose or adapter, ensuring safe, leak-free operation. The FKM (Viton®) elastomeric seal provides high resistance to temperature and aggressive fluids.

This non-screwed, one-piece design includes a knurled self-locking metal cap that stays secure even during system vibration. With a max operating pressure of 9,137 PSI and coupling under pressure up to 5,801 PSI, it’s built for demanding conditions. Zinc-nickel coating delivers long-term corrosion resistance in industrial environments.
