Parker BH4-61 Female Pipe Rigid Nipple Fitting 3500 Psi

Product Description

The PARKER BH4-61 is a female pipe rigid nipple fitting designed for high-pressure hydraulic and fluid system applications. Constructed from brass with an NPTF threaded connection, this straight fitting delivers a maximum working pressure of 3,500 psi and an overall length of 1.94 inches. The Series 60 design meets ISO 7241-1 Series B standards, making it a reliable choice for licensed plumbers, hydraulic system technicians, and industrial maintenance professionals who need a leak-resistant threaded connection in demanding service environments.

This fitting is suited for both mobile equipment and stationary industrial hydraulic lines. Its temperature range of -40 degrees F to 250 degrees F makes it appropriate for year-round outdoor and indoor installations. Typical applications include food and chemical processing systems, compressed gas lines, industrial hydraulic circuits, mobile equipment hydraulic assemblies, and water and coolant distribution lines. The NPTF thread form creates a mechanical seal through thread interference, reducing dependence on supplemental thread sealants in many installations.

Key Features

• Maximum working pressure of 3,500 psi for high-demand hydraulic service
• Brass construction for corrosion resistance in fluid and chemical handling systems
• NPTF threaded connection provides a pressure-tight mechanical seal
• Straight body geometry simplifies inline hose-to-pipe terminations
• Rated from -40 degrees F to 250 degrees F for broad operating range
• Meets ISO 7241-1 Series B standards for international system compatibility

Compatibility

Designed for use with food and chemical processing lines, compressed gas systems, industrial hydraulic lines, mobile equipment hydraulic circuits, and water and coolant lines requiring a 1/2 inch NPTF female pipe rigid nipple connection.

Installation Notes

Installation should be performed by a qualified plumber or hydraulic technician. Depressurize and drain the hydraulic or fluid system completely before removing or installing any fittings. Inspect threads on both the fitting and mating component for damage before assembly. Consult applicable system pressure ratings and local codes before placing the fitting into service.
