Fittings for 3/8 ID rigid tubing

This six-pack of PrimoChill RevolverSX compression fittings is built for custom-loop builders who run 3/8 in. ID by 1/2 in. OD rigid tubing in PETG, PMMA or copper. Each fitting uses industry-standard G 1/4 threads so it threads directly into most water-blocks, radiators and reservoirs without adapters.

Brass core with nickel plating resists corrosion

The G 1/4 threaded core is machined from brass and plated in bright nickel to withstand long-term coolant contact without degradation. SpectraX powder-coated caps add a durable colour layer that does not flake or fade, keeping the loop's appearance consistent over years of service.

Diamond-knurl caps in 34 colour options

Knurled compression caps give a secure grip for hand-tightening while the 34 available colours let builders match or contrast tubing, coolant and component accents. The fittings are sold as a six-pack with no additional tools or seals included, so plan the exact quantity your loop topology requires.

Questions about this item

How do I install the PrimoChill RevolverSX fittings on 1/2 in. OD rigid tubing, and what step is often missed?

Chamfer and deburr the tube end, slide the compression cap on first, then push the tube fully over the G 1/4 threaded brass core before tightening the diamond knurl cap to seal the O-ring.

What maintenance or replacement will the RevolverSX fittings need over time?

Inspect the O-rings inside each nickel-plated brass core during loop draining; replace any that have flattened or cracked, and re-torque the diamond knurl caps after the first few thermal cycles.

What limit appears first when the RevolverSX fittings run under sustained load?

The practical limit is the rigid tubing material — PETG, PMMA or copper — since the SpectraX powder-coated caps and nickel-plated brass core are rated for continuous loop temperatures.
