Heavy Haul Heavy Series 08S Test 20 Coupler, Poppet Check Valve, 24° Taper, FKM Seal

Engineered for high-pressure performance and ease of use, this Test Coupling is part of the trusted Test 20 Series with M16x2 connection thread, designed for efficient system pressure monitoring, fluid sampling, and venting without tools or downtime. With a robust steel body and a reliable piston valve, this coupling is ideal for hydraulic applications demanding precision and durability. The integrated poppet check valve ensures leak-free sealing, while the Viton® (FKM) seal offers excellent chemical and temperature resistance.

This one-piece, non-screwed design features a knurled self-locking metal cap that stays secure even under system vibration. Built for convenience and safety, the coupling handles full system pressure up to 9,137 PSI, with pressure connection possible up to 6,090 PSI. Its zinc-nickel surface treatment delivers superior corrosion protection. Whether used for heavy haul applications, diagnostics, maintenance, or contamination monitoring, this test coupling delivers reliable performance under the most demanding conditions.
