Replacement O-Ring for 13mm Fittings

This Alphacool silicone gasket replaces the seal on 13mm hard-tube compression fittings. It is manufactured in black silicone and carries part number 1010971. The ring is designed for G1-inch threaded connections used in custom liquid-cooling loops.

Suitable for Loop Maintenance

Builders servicing existing Alphacool HT fittings or compatible 1-inch thread components can use this O-ring to restore a watertight seal. It also fits the Lighttower adapter for Phobya DC 260 and 400 pumps. Anyone needing a different inner diameter, a different material such as EPDM, or a fitting kit rather than a single seal should look elsewhere.

Critical Specification: 13mm Hard-Tube Compatibility

The decisive factor is that this O-ring is sized for 13mm outer-diameter hard tubing used with Alphacool HT compression fittings. Its cross-section measures 1.5 mm and the overall diameter is 32 mm. If the tubing or fitting in your loop uses a different standard, this gasket will not seal correctly.

Questions about this item

Will this O-ring seal my existing 13 mm hard-tube fittings?

It is made for 13 mm compression fittings with a G1 inch thread, matching the 32 × 1.5 mm groove on those parts.

How can I confirm the seal is working after installation?

Pressurise the loop and watch the joint; no coolant should appear at the fitting collar.

What comes in the package and what else do I need?

Only the black silicone O-ring is supplied; the fitting body and compression nut are separate.
