Yale FY Hydraulic Fittings

High Pressure Fittings 700 bar | 28 Parts | Multiple Thread Standards

The Yale FY range comprises 28 high-pressure hydraulic fittings designed for versatile combinations of hydraulic cylinders and accessories. All fittings are designed for a maximum system pressure of 700 bar. Yale supplies double nipples, elbows, tees, crosses, connections, reducers and adaptors covering multiple thread standards (3/8 NPT, 1/4 NPT, BSP, M14, M18, M20, M22).

High-pressure fittings for Yale 700 bar hydraulic systems

Yale documentation states the FY fittings are useful for versatile combinations of hydraulic cylinders. Yale notes an important operational guidance: for improved sealing of 3/8 NPT connections, use 2 layers of teflon tape and tighten accordingly.

Specialist sets include FY-703 (connecting set for 4/3-way valve to HPS hand pumps) and FY-201 (hose connector for TWAZ 2000 bar hand pumps).

Q: What's the FY-703 connecting set?
