Common Applications

TFHRKN38H is a G1/4 brass compression fitting sized for 10x16mm soft tubing, equivalent to 3/8 in ID and 5/8 in OD. The inner barb is dimensioned for a 10mm internal bore, and the outer threaded collar clamps the 16mm-OD tube wall against it for a leak-tight seal. The collar carries a diamond-knurled texture to give fingers grip during install and to reduce slip when the loop is under thermal stress. Standard G1/4 male thread mates to any compatible reservoir, pump top, radiator, or CPU/GPU block port. Finishes include black, silver, white, and gold.

Frequently Asked Questions

Q: What exact tubing size is this fitting for?

A: Soft tubing with 10mm ID and 16mm OD, also marked as 3/8 in ID and 5/8 in OD. Other sizes such as 9.5x12.7mm or 13x19mm do not fit.

Q: Will it work on EPDM, PVC, or Norprene soft tube?

A: Yes, on any flexible water cooling tubing that matches the 10x16mm dimension. PVC clears the barb most easily; stiffer materials may need brief warming with hot water.

Q: What is the thread on the case side?

A: Standard G1/4 male, the universal PC water cooling thread, with a pre-installed O-ring at the base.

Q: How tight should the outer collar be?

A: Hand-tight against the soft tube wall, then a small additional turn with the collar; do not use a wrench.

Q: What is included?

A: One fitting, consisting of the male G1/4 body with internal barb plus the outer compression collar.
