Common Applications

The TDKN-T14 is a hand-tighten compression fitting that terminates 14mm OD rigid PETG or acrylic tubing into any standard G1/4 BSPP port found on water blocks, radiators, reservoirs and pump tops. The body uses a knurled outer ring that lets builders thread the collar onto the base without tools, while an O-ring stack inside the collar seals against the tube wall. Each fitting is sold as a single piece and pairs with most aftermarket 14mm hardline kits. Builders typically use one fitting per tube end, so a closed loop budget should plan two fittings per run.

Frequently Asked Questions

Q: What tubing diameter does the TDKN-T14 accept?

A: It is built for 14mm outer-diameter rigid tubing in PETG or acrylic. It will not seal against 12mm or 16mm OD tubing or soft tubing.

Q: Is the thread G1/4?

A: Yes. The base thread is standard G1/4 BSPP, which mates with every common water-cooling block, radiator and reservoir port.

Q: Does it need a wrench to install?

A: No. The knurled collar is designed for hand-tighten installation. A snug hand-tight is sufficient once the tube is fully seated against the inner shoulder.

Q: How many fittings come in the package?

A: This listing is a single fitting. Plan two fittings per tube run between components.

Q: Can it be reused after a teardown?

A: Yes, as long as the internal O-rings remain intact. Inspect the rings for cuts and replace if compromised before re-pressurising the loop.
