1¼" Polypropylene Bulkhead Fitting

The Banjo TF125 is a 1¼-inch bulkhead tank fitting moulded from black polypropylene. It installs through a tank wall to create a leak-resistant outlet or inlet for liquid transfer systems. The fitting ships new with an EPDM gasket included to seal the flange face against the tank surface.

Installers needing a corrosion-resistant tank port

This part suits plumbers and maintenance crews fitting chemical tanks, irrigation reservoirs or water-storage vessels where polypropylene handles the media. It is not for installers who require a metal body, a different thread standard or a gasket material other than EPDM. Buyers needing a smaller or larger nominal bore must select another model.

Double female NPT threads at 300 psi

Both sides of the fitting carry 1¼-inch female NPT threads so pipe or adapters connect on the interior and exterior of the tank wall. The assembly is rated for a maximum operating pressure of 300 psi. Verify that the tank wall thickness and the mating pipe schedule are compatible with this thread form and pressure class.

Questions about this item

How do I install the TF125 bulkhead fitting and which step is most often done incorrectly?

Insert the fitting through the tank wall, seat the EPDM gasket flat against the surface, then tighten the back nut by hand plus one-half turn with a strap wrench; over-tightening cracks the polypropylene body.

What maintenance will the TF125 need and when should the gasket be replaced?

Inspect the EPDM gasket annually for hardening or cracks; replace it at the first sign of weeping or after any system pressure test that exceeds 300 psi.

What is the first limit the TF125 reaches under sustained pressure?

The polypropylene body is rated for a maximum operating pressure of 300 psi; sustained operation at or above that pressure risks permanent deformation and leakage.
