Parker Hydraulic Valves

NPT fittings seal via thread deformation and typically require sealant, while NPTF (dryseal) fittings achieve a tighter metal-to-metal seal without sealant. For high-pressure hydraulic systems where leakage is critical, NPTF is often preferred. Check your system's port type and pressure rating before selecting.

Parker quick-connect couplings, such as the 6600 Series bodies and FEM Series plugs, are designed to Parker's specifications. While some interchange standards exist (e.g., ISO 7241), always verify dimensional and pressure compatibility with your existing couplers to avoid leaks or failure.
