8 Pieces Drip Irrigation Barbed Tee Fittings 1/2 Inch Universal Connectors, Plastic Soaker Hose End Stop, Black

Very difficult to use on standard 13mm /1/2 irrigation pipe. The high ridges make it very difficult to fit compared to other brands.Also, it does not work on soaker hoses or pipe to soaker hose as is a commoner way to use them compared to other brands. This brand fits the soaker hose but leaks.

I ordered these to build my rainwater harvest system, connecting small lengths of 1/2 inch garden hose pipe. Bit tricky to get on when cold, but some gentle heat allowed the pipe to fit over the barbs. Would advise using a jubilee clip on each connection to ensure the it is water tight.

I routed some hose and needed some 90 degree bends. Not really a lot to say, but garden hose needs softening in a mug of hot water before trying to push these in.

Does what it is supposed too - used in professional plastic drip hose

Easy to fit. No leaks
