Weldless Bulkhead 1/4" Compression Fitting Inside. For installing 1/4" temperature sensors.

  • $25.00

CNC machined from a solid hex of 304 stainless steel. This design is for installing a 1/4" temperature sensor through a vessel wall without welding! Single-piece design prevents the leakage and cleaning hassles from weldless fittings put together from plumbing parts and washers.

The most unique feature is the Face-Sealing silicone o-ring grooves.  Grooves are machined in the face of the fitting and locknut, eliminating the leakage associated with weldless fittings that attempt to seal near the threads.  Both the fitting and the included locknut are groove machined for the o-rings.


NEW design requires 1/2" hole and has 1/2" X 20UNF threads.  Also requires a wrench or channel locks that can grab a 1-1/8" hex.

Includes the 1-piece weldless bulkhead, 2 silicone o-rings and the specially machined locknut as well as the compression nut and 2 silicone o-rings for the compression fitting.

    I was a bit concerned about the cost of this thing but when you get it, you can tell how well made it is. I put two of them in my MLT and they're great. Don't screw around with random compression fittings; this is a leak-free solution.
