Eaton Weatherhead 1368X8X4 Brass Compression Fitting 1/4-18 1/2 In 150 PSI

SKU CH-K7VB-EX2QF

A brass compression fitting connecting 1/4-18 pipe to 1/2 inch copper tube, rated 150 PSI from -40 to 200 F, with nut and sleeve included

  • Product typeAccessories & Compressors
  • Brass construction resists corrosion for long service life
  • Compression design seals 1/2 in copper tube without soldering
  • Rated 150 PSI for reliable hydraulic and pneumatic connections
  • Operating range -40 to 200 F suits extreme environments
  • Meets SAE and DOT standards for regulated applications

Brass Compression Fitting for Copper Tube

The Eaton Weatherhead 1368X8X4 is a brass male connector built to join 1/2 inch copper tube to a 1/4-18 pipe thread using a compression seal. It includes the nut and sleeve required for assembly and is rated for 150 PSI service in fluid or gas lines.

Temperature Range and Pressure Rating

The fitting operates continuously from -40 to 200 F while maintaining its 150 PSI pressure rating under SAE and DOT standards. Brass construction resists corrosion without adding electrical noise or measurable power draw to the connected system.

Sustained Load Behaviour Under Pressure

Under sustained 150 PSI load the compression joint holds seal integrity across the full -40 to 200 F temperature span without creep. The brass body and included nut and sleeve assembly meet SAE and DOT requirements for long-term service in fixed piping installations.

Questions about this item

How do I install the 1368X8X4 fitting without overtightening the 1/4-18 threads?

Slide the nut and sleeve onto the 1/2 inch copper tube, insert the tube fully into the body, then tighten the nut one and a half turns past finger-tight to seal the compression joint without stripping the 1/4-18 threads.

Which parts of the 1368X8X4 will need replacement after repeated thermal cycling between -40 and 200 F?

The brass body resists corrosion, but the copper sleeve and nut can work-harden or deform after many heat cycles; plan to replace the sleeve and nut if the joint is broken and remade.

At what pressure does the 1368X8X4 reach its rated limit during continuous operation?

The fitting is rated for 150 PSI; sustained pressure at or above this value is the first limit encountered under continuous use.
