TRI Thread Fittings  UNIVERSAL THREADS

The pneuforce.com TRI THREAD fittings have been developed to connect with global fluid power products.  With many factories in North America using a mix of NPT (American) and BSPP & BSPT (Europe and Asia) threads, there is some confusion as to what male threads should be used or stocked by fluid power users.  



Therefore the universal thread form of the TR THREAD series has been developed to enable the connection of 1/8, 1/4, 3/8 and 1/2 male threads into the following female thread forms. NPT, NPSF, BSPP(G), BSPT(R)



Tubing sizes available:

• INCH 1/8”, 5/32”, 3/16”, 1/4”, 5/16”, 3/8” & 1/2

• METRIC 4mm, 6mm, 8mm, 10mm & 12mm.

Due to the design of this thread form, the time taken to install the fittings has been dramatically decreased. The following procedure should be used when installing TRI THREAD fittings.By hand, screw the TRI THREAD fitting into the female thread until the O ring seal pushes against the face of the component.  Using a suitably sized wrench, continue to tighten the fitting by turning clockwise by a further 1/4 turn.



Unlike a tapered thread, the seal is made via an O ring seal which is captive in the TRI THREAD. It is not an

interference fit like that of male and female tapered threads. The TRI THREAD can seal repeatedly.
