Legris 0105 08 17 8mm Compression x 3/8" BSPT Straight Coupling 10 Pack

SKU CH-X6ZC-0GFHM

Connects 8 mm tubing to 3/8 inch BSPT threads, rated to 1450 psi and -40 to 482 °F, supplied in a 10 pack

  • Ready for high-pressure systems up to 1450 psi
  • Operates from -40 to 482 °F for extreme environments
  • Compression-to-BSPT design joins 8 mm tube to 3/8 in pipe
  • Brass construction meets AFNOR, CETOP, CNOMO and ISO standards
  • Pack of 10 fittings with 17 mm hex for quick installation

Brass compression fittings for 8 mm tube

These brass straight couplings connect 8 mm tubing to a 3/8 inch male BSPT thread using a compression seal. The pack contains ten identical fittings for plumbing, pneumatic or hydraulic circuits that require a straight, leak-tight joint. Each fitting has a 17 mm hex for spanner tightening.

Pressure and temperature envelope

The fittings are rated to a maximum working pressure of 1450 psi and operate across a temperature range of -40 °F to 482 °F. Compliance is listed against AFNOR, CETOP, CNOMO and ISO standards, so the limits reflect those specifications. Installations exceeding either the pressure or temperature boundaries will need alternative components.

Thread and tube compatibility check

The critical specification is the 3/8 inch male BSPT thread paired with an 8 mm (19/64 inch) tube compression end; both dimensions must match the mating parts exactly. If the port uses a different thread form or the tubing has a different outside diameter, these couplings will not seal.

Questions about this item

Should I buy the 10-pack or individual fittings for my 8mm tubing?

The 10-pack supplies ten identical brass straight adapters, each joining 8mm compression tube to a 3/8" male BSPT thread, convenient for multiple connection points.

What does the 1450 psi rating mean when the fitting is installed?

It indicates the maximum working pressure the brass body and compression seal can sustain at up to 482°F, provided the tube is correctly tightened to the 17mm hex.

How does the BSPT thread affect sealing compared with parallel threads?

The 3/8" male BSPT taper creates a pressure-tight seal as it engages, so thread sealant or PTFE tape is normally applied to ensure leak-free performance up to the rated pressure.
