TAILONZ PNEUMATIC 3/8 Inch Barb x 1/4 Inch NPT Brass Female Hose Fitting Connector（Pack of 10）

Resorted to a small Phillips for the clamps.

Great product

Great item.

As Avery C. and Marc Cram noted, these fittings are exactly the size of the ID of the intended hose as opposed to being 1/32 oversized as many other of this type of fitting are. This makes it imperative to use a strong clamp to keep them tight in the hose.I generally prefer using a ferrule rather than a hose clamp to hold these, since ferrules are more streamlined and less prone to failure.Whenever the hose diameter permits, I now use Pex expander rings rather than brass ferrules (which are more size adaptable). They are quicker, smoother and more easily removed if needed.I use the Pex rings for both air and water hose and they work GREAT!

These are nice looking brass fittings, but the barbs only measure .250" so when installed on a 1/4" hose they fit loosely. Other fittings that I have that say they have a 1/4" barbs mean they are for a 1/4" hose and the barbs measure about .290" so they fit tight on the 1/4" hose so they don't come as near leaking or blowing off. With the clamps tightened down good fittings will probable be alright but would rather to have had them fit tighter on !/4" hose so this is reason for only 4 stars.

They seem OK, they were the right size, but they clearly aren't machined to the standards or quality that the big hardware store versions are.Too bad, as I wasn't trying to cheap out when buying these. The reviews would have suggested a better product.I won't rate them too badly, as they fit the description, they only clearly are not machined at high quality.Time will tell if they actually last.

These fittings are used for the air hose on my drywall spray rig they fit like a charm work really good

High quality of manufacture - for $3.00 apiece (per Brass hose Barb Fitting) I can't complain.PROJECT I COMPLETED:Along with these brass hose barb fittings...I used these Stainless Hex nuts --> https://www.amazon.com/gp/product/B078TLNJ9P/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1and this 3/8" clear hose tubing...https://www.amazon.com/review/review-your-purchases/?asin=B07PY96B3Z&channel=YAcc-wr-thankyou&ref_=ryp_hz_thnk_l_2&pinnedAsins=B07X3FXTYXalong with drilling a 1/2" hole near a bottom corner of this plastic tray...https://www.amazon.com/review/review-your-purchases/?asin=B07PY96B3Z&channel=YAcc-wr-thankyou&ref_=ryp_hz_thnk_l_2&pinnedAsins=B07X3FXTYXI was to make an overflow catchbasin / drain for an occasional leakage problem in my house.
