Made for 1/2" ID x 3/4" OD tubing
Barrow makes this fitting for 1/2" ID x 3/4" OD (19/13 mm) soft tubing. The tube slides over the barb on the base and the collar presses it down from the outside, so it cannot slip off under pressure the way a tube on a plain barb can.
Fitting it
Screw the base into a G1/4" port by hand, push the tube over the barb as far as it goes, then screw the collar down over the tube until it is snug. The male thread is sealed by an O-ring.
Brass with a double-protected finish
Barrow machines the body from H59 brass and protects the surface with what it calls a double electroplating process, which it says gives a fine texture that is solid and durable.
Non-slip diamond knurling
The outside carries a diamond knurl pattern. Barrow says it gives a sure grip when you screw the part in by hand.
Standard G1/4" connections
The thread is the standard G1/4" of PC water cooling, so the fitting works with blocks, radiators, reservoirs and pumps from other makers as well as Barrow's own.
