Parker S71-3C16-20F Hydraulic Hose Valve Fitting 1-1/4 in

Product Description

The PARKER S71-3C16-20F is a stainless steel hydraulic hose valve fitting rated for 4,000 psi service. It accepts a 1-1/4 inch thread size and is engineered for use in high-pressure hydraulic circuits where reliable fluid control and leak-free sealing are critical. The stainless steel construction provides corrosion resistance in demanding environments. This fitting is installed by hydraulic technicians, industrial maintenance professionals, and fluid power specialists working on mobile or stationary hydraulic systems. The operating temperature range spans from -35 degrees F to 250 degrees F, making it suitable for both cold-start and elevated-temperature hydraulic applications.

This valve fitting is applied in industrial and mobile hydraulic systems where a secure, pressure-rated connection between hose assemblies and valve bodies is required. Typical installation scenarios include hydraulic power units, cylinder circuits, and high-pressure fluid distribution manifolds. It is well-suited for environments where stainless steel is specified due to fluid compatibility requirements or exposure to corrosive media. The 1-1/4 inch thread size accommodates larger-bore hydraulic lines common in higher-flow industrial circuits.

Key Features

• 4,000 psi pressure rating for high-pressure hydraulic service
• Stainless steel construction for corrosion resistance and durability
• 1-1/4 inch thread size suits larger-bore hydraulic hose assemblies
• Operating range of -35 degrees F to 250 degrees F for broad thermal compatibility
• Valve fitting design provides secure connection at hose-to-valve interfaces

Compatibility

Designed as an OEM-style replacement or direct-fit valve fitting for high-pressure hydraulic hose assemblies requiring a 1-1/4 inch stainless steel connection at 4,000 psi rated service conditions.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before disconnecting or installing any fittings. Use the appropriate torque and thread-sealing method specified by the system designer for the thread type in use. Inspect threads and seating surfaces for damage before assembly to prevent leaks under pressure.
