Connects Fractional Tubes To Male NPT Thread

The Superlok SFBTI consists of two compression tube fitting connections with a female NPT port on the branch. These are great for connecting equipment in series or splitting NPT feed lines into two.

This fitting series also features Superlok's patented i-Fitting technology on all tube fitting connections between 1/4" and 1".

Connects Fractional Tubes To Male NPT Thread

Do you need to bring two separate pipes together using a fitting with a female NPT thread? We offer Superlok branch tees that easily match up with size-appropriate male threads.

You’ll create a secure connection within your tubing system, all without the hassle of other traditional options. You can screw the two ends together, and from there you can implement the other two fractional tubes into the body and tighten the nuts.

High-quality materials and interior finishing practices improve flow through the fitting while reducing the likelihood of leaks and other breaches. You can use these handy pieces of hardware in multiple industries, as we carry numerous sizes.

Having to handle two distinct flows, either by diverting them or bringing them together, puts a lot of strain on these branch fittings. That said, Superlok specifically designs its fittings to handle extreme temperatures, pressure and vibrations without risking structural integrity. Mako Products has worked in conjunction with Superlok to produce the i-Fitting system, which adds another layer of security by acting as a built-in gap gauge.

You’ll produce the perfect level of tightness by following the red inspection check ring, which will pop off the body when you find the sweet spot.
