3/8 in. x 3/8 in. Compression x Female NPT White Nylon Adapter
3/8 in. x 3/8 in. Compression x Female NPT White Nylon Adapter
Overview
The Midland 17154N is a white nylon adapter joining a 3/8 in. compression tube to a 3/8 in. female NPT (FIP) thread. It lets soft nylon or poly tubing terminate at a male-threaded pipe, valve, or pump fitting without solder. Rated to 125 psi and -40°F to 200°F, the corrosion-resistant nylon body suits water and chemical lines that would attack brass.

Typical Applications
Use this adapter to land a 3/8 in. tubing run on a 3/8 in. male NPT port: connecting metering-pump and valve fittings, filter housings, gauges, and injection points on water-treatment and chemical-feed plumbing. The nylon construction is preferred where a non-metallic, corrosion-free tube-to-thread transition is needed.

FAQ
Is the FIP end female threaded?
Yes. FIP means female iron pipe, i.e. a 3/8 in. female NPT thread that screws onto a male pipe nipple.
Does the NPT end need sealant?
Yes. Use PTFE tape or pipe dope on the male thread you are connecting to; do not over-tighten nylon female threads.
What is the maximum pressure?
125 psi, within -40°F to 200°F.
Do I need a tube insert?
For soft poly tubing, a stiffening insert helps the nylon ferrule seal without collapsing the tube.
