FAQ

Is it metal-on-metal or with O-ring sealed?

Modern G1/4 extenders use O-ring seals on the male/female threads. Hand-tight is usually sufficient — overtightening can damage the O-ring.

What size port does it use?

G1/4 thread is the standard for PC water cooling. Check the product specifications above for any deviation.

Is this Barrow part compatible with non-Barrow loops?

Yes. G1/4 is industry-standard, so brand mixing works in most cases. Confirm any specialty connectors (Quick-Disconnect, proprietary backplates) before mixing brands.
