RUKO SCE-DIN5158-G1-1/4x11 Test Coupling, G 1 1/4 BSPP, M16x2 Test Port, 630 bar, Steel, Zinc-Nickel

The RUKO SCE-DIN5158-G1-1/4x11 test coupling provides a reliable connection point for pressure monitoring, venting, and sampling in hydraulic systems. Its poppet valve design ensures self-sealing upon disconnection, minimizing fluid loss and contamination. The zinc-nickel plating offers corrosion resistance without hexavalent chromium, making it suitable for demanding industrial environments.

Highlights

• System connection: G 1 1/4 BSPP parallel thread
• Test port connection: M16x2 thread
• Maximum operating pressure: 630 bar (9135 psi)
• Body material: steel with zinc-nickel plating (Cr(VI)-free)
• Seal material: NBR (Buna-N), temperature range -30°C to +100°C
• Hexagon size: 41 mm
• Complies with DIN EN ISO 15171-2

In daily use

Install the coupling in a hydraulic line using the G 1 1/4 thread. Connect a pressure gauge or diagnostic equipment to the M16x2 test port. The poppet valve opens automatically when the test hose is attached and closes when removed, preventing leakage. The zinc-nickel surface withstands harsh conditions, and the NBR seals are compatible with mineral oils and many hydraulic fluids.
