Dryseal Pipe Threads

 

NPTF threads are formed to have a 1.78 taper with tightly machined tolerances to provide contact at the crest and root of the thread as well as the flank. The metal-to-metal seal of the thread crest, root and the flank together provide a complete seal to help prevent the possibility of spiral leakage. NPTF threads also provide the holding power for the connection while in high-pressure service, which limits the reliability of the seal the threads are making with the female port. For high-pressure applications where constant vibration is running through the hydraulic systems, hydraulic fittings with SAE straight threads which connect to female or male ports are recommended.

 

Torque values of hydraulic fittings during installation may vary. Factors which may cause torque values to differ are: Type of construction (Bar stock VS. Forged), different types types of plating, and different tolerances between male and female threads.


Assembly instructions

 

1.     Visually inspect the fitting and mating port and remove any burr of foreign matter which may be present.

2.     Apply thread sealant if needed to the male threads. Keep the first 2-3 threads free from sealant so you do not contaminate the hydraulic system.

3.     Install to a finger tight position.

4.     Using a wrench turn the fitting approximately 2 2-1/2 turns past the finger tight position.
