Phobya 13mm G1/4 Barb Fitting

This Phobya barb fitting connects 11-13mm inner-diameter hoses to a G1/4 thread in custom liquid-cooling loops. The black nickel-plated brass body includes an integrated Perbunan O-ring for a reliable seal. It suits builders assembling new water-cooling circuits with PVC, PU, PA, silicone or PE tubing.

Installation notes and common issues

Thread the fitting into a G1/4 port by hand and finish with a gentle turn using a suitable wrench on the hex flats. The barbed end requires a hose clamp or zip tie to prevent the tube from slipping off under pressure; skipping this step is the most frequent cause of leaks. The O-ring stays seated in its groove during normal tightening.

Who this suits and who should look elsewhere

Builders using 11-13mm ID tubing and standard G1/4 components will find this fitting a cost-effective choice. It is not for systems that demand compression or push-lock fittings, nor for loops requiring angled or rotary adapters. Buyers needing coloured or nickel-free finishes must select a different model.

Questions about this item

How can I confirm the G1/4 thread is sealing correctly after installation?

Tighten the fitting until the integrated Perbunan O-ring compresses fully against the port, then pressurise the loop and watch for any moisture at the thread joint.

The box contains one black nickel FatBoy barb — what else must I source to complete the connection?

You will need 11 to 13 mm inner-diameter hose (PVC, PU, PA, silicone or PE) plus hose clamps or zip ties, which are not included.

This model is listed as 13 mm FatBoy — is there a smaller-barb version under the same MPN?

No, 63251-BULK is supplied only as a single 13 mm (1/2 inch) G1/4 barb fitting with O-ring.
