  • Corrosion-resistant 316 stainless construction withstands harsh chemicals

Purpose and fit

The Banjo TF125SS is a bulkhead tank fitting designed for 1-1/4 inch female NPT connections on curved or flat tank walls. It suits industrial and agricultural plumbing systems that require a reliable drain or trap point without bolt-hole mounting.

Build and connections

The fitting body is made from 316 grade stainless steel with an EPDM gasket for chemical compatibility. Both the inside and outside connections are 1-1/4 inch female NPT threads, allowing direct pipe engagement on either side of the tank wall. The assembly handles pressures up to 300 psi and temperatures from -20 to 300 degrees F.

Upgrade context

This fitting replaces plain bulkheads or lower-grade alloys where corrosion resistance and high-temperature sealing are required. The jump is worth it when the media or environment demands 316 stainless performance and a wide temperature range.

Questions about this item

What does the 1-1/4" FNPT thread on this Banjo TF125SS bulkhead fitting cap in practice?

The female NPT threads accept 1-1/4" male pipe connections on both the tank side and the outlet, rated for 300 psi at up to 300 °F.

What tank wall thickness and hole size does the 316 SS bulkhead body require to mount?

The flange bolts flat or curved tank walls with no bolt holes; you drill a single clearance hole matching the 1-1/4" body and seal with the supplied EPDM gasket.

How is the TF125SS installed, and which step do installers most often get wrong?

Insert the body through the tank hole, seat the EPDM gasket on the flange, then thread the 1-1/4" FNPT connections; the common error is tightening pipe joints before the gasket is fully compressed.
