Quick-release nylon couplings for 12.7 mm soft

This kit provides two HF quick-release couplings made from black nylon, model 17452, designed for 12.7 mm outer diameter and 7.6 mm inner diameter soft tubing. Each coupling measures 95 mm in length and 27 mm in diameter. The nylon construction prevents galvanic reaction when used alongside copper or aluminium components in a custom liquid-cooling loop.

Barrier-rim design secures hose without extra clamps

A metal retaining ring with hooks grips the tubing behind a barrier rim, delivering high tensile strength that resists pull-off under pressure. Screw caps lock the release mechanism against vibration or movement, while a double seal maintains leak-free operation. The fittings suit any 3/8" ID x 1/2" OD soft tubing, not only Alphacool TPV hose.

Nylon body withstands long-term coolant contact

Because nylon does not react with common loop metals, the couplings avoid corrosion or degradation during continuous circulation. The screw-cap lock and double seal remain effective through thermal cycling and pump vibration, so connection integrity is preserved over extended operating periods rather than just initial assembly.

Questions about this item

What is the maximum hose outer diameter the 17452 coupling can grip?

The coupling accepts 12.7 mm outer-diameter soft tubing, matching 1/2" ID hose.

How much heat can the nylon body withstand during continuous liquid flow?

Nylon resists typical water-loop temperatures and will not corrode against copper or aluminium components.

Which tubing size must I already have for this 12.7/7.6 mm kit to seal correctly?

You need 3/8" ID x 1/2" OD soft tubing; the barbed rim locks onto the 12.7 mm outer wall.
