POLY HOSE TEE 1/4TX1/4TX1/8P
The nylon tube fittings (connectors) worked as advertised. They arrived when I expected them. I used them to connect lengths of one quarter inch inside diameter polyurethane tubing.
great products and super prices, Thank you! Bruce
The Black Polyethylene fittings break easily: the 1/8 NPT x 3/8 barbed is VERY weak next to the hex nut portion. I broke two of them just installing them. The first one (used for the bottom fitting of a sight tube) broke without my realizing it during installation, causing a slow fuel leak that flooded the interior of my wing. The second, (at the top of the sight tube) broke while bending the tube during the replacement of the first fitting. Not sure why AS&S sells the polyethylene version, but theyre quite unsuitable for aircraft use. Advice is to use the nylon version.
I installed these in my pitot-static system. The fittings break easily. I am switching to all brass/aluminum fittings.
I installed tee all tube P/N 0715-015 fittings in my pitot-static system. After one year two of them broke at the same time causing erroneous indications (speed). Dangerous thing, highly not recommended.

This would be the inside dimension of the tube.
We offer a few 1/4" I.D. rubber hoses that can be used. Aeroquip 306-4 & Tygon 05-00944 are just a couple common ones.
Yes, the pipe thread on these fittings are called out as NPT.
There are a few, it depends on material and tubing size. 0710-153, 0711-153,0710-158, and 0711-158.
