Polypropylene 'L' 90 Degree Elbow 3/8IN Barbs

Comment:
I have tried these with both 5/16ID (brand x) and 3/8ID Primochill hoses. There was a tighter fit on the 5/16 hose of course, and no hose clamp was required. Entry into the Primochill 3/8 tubing was very snug, so you could probably get away with no hose clamp there too (but there's only one barb rib, so I used hose clamps). The hose clamp surface is good and level, and is 11mm (7/16") wide for use with worm gear hose clamps if you need that much room. All in all a very good product.
