G1/4 13 mm Hard-Tube Fitting

This compression fitting connects 13 mm outer-diameter rigid tubing to any component with a standard G1/4 thread. The knurled body allows hand tightening without tools. It suits custom loops built with hard acrylic, PETG or metal tubes. Buyers needing push-in quick-disconnects or barb fittings for soft tubing cannot use this part.

Sustained Loop Integrity

The compression design clamps the tube wall evenly around its full circumference, maintaining seal pressure through thermal expansion cycles. Deep black finish resists coolant staining during long-term operation. No flow-restriction data is supplied, so system builders must verify loop pressure drop independently.

Installation Notes

Slide the compression nut and olive onto the tube, seat the tube fully against the internal stop, then tighten the nut until the olive compresses. Over-tightening can crack acrylic or PETG; under-tightening leaves a leak path. No tube-cutting guide or deburring tool is included.

商品問答

Does the G1/4 thread on the 17189 fitting leak after the loop runs hot all day?

The compression design seals hard 13 mm tubes to a standard G1/4 port and is built for continuous operation without weeping.

What tube size and block ports must I already have to use the 17189 fitting?

You need 13 mm OD rigid tubing and components with G1/4 threads such as radiators, blocks or reservoirs.

Will the 17189 fitting thread into the G1/4 ports on my older CPU block and radiator?

Yes — the G1/4 thread is the long-standing standard, so it mates with legacy blocks and radiators that use the same pitch.
