Part Number: 5000

NPTF Pipe Female Coupling

Product Overview

The Delphi Fittings Part 5000 is a high-quality NPTF Pipe Female Coupling, meticulously designed to connect two male NPT (National Pipe Taper) or NPTF (National Pipe Taper Fuel / Dryseal) threaded pipes or fittings of the same size. Manufactured from durable carbon steel and featuring NPTF Dryseal threads, this coupling ensures a strong, mechanical, and leak-proof seal for demanding hydraulic and pneumatic applications. Its robust construction provides reliability in various industrial environments.

Applications

The versatile design of the Part 5000 NPTF Female Coupling makes it suitable for a wide array of applications, including but not limited to:

General hydraulic systems in industrial machinery
Pneumatic circuits and air line connections
Agricultural equipment and implements
Construction machinery fluid power systems
Automotive fluid transfer lines (e.g., fuel, oil, air)
Connecting rigid pipes, flexible hoses (via adapters), valves, and manifolds
Maintenance and repair operations requiring reliable pipe joints

Installation & Usage Guidelines

Ensure both male threads to be connected are clean, free from debris, and undamaged.
Align the coupling and male fittings properly to avoid cross-threading.
Hand-tighten the male fittings into the coupling initially.
Use appropriate wrenches on the male fittings to tighten. Apply torque according to industry best practices or specific equipment manufacturer recommendations.
NPTF threads are designed for a dry seal. However, for very high pressures or to ease assembly and prevent galling, a compatible thread lubricant (not a sealant that obstructs thread engagement) may be used sparingly on the male threads. If standard NPT male fittings are used, a suitable thread sealant will be required on the male threads.
Avoid over-tightening, which can damage threads or crack the fitting.
