Review on 🚰 30 Pack DripMaster 67431 Assortment by Orbit by Guerdon Draper

Parts 'feel' well made and a decent range is provided as a starter kit. However, the few parts I have tried so far have not worked well with the (new) Rain Bird 1/4" pipe. Both plugs and tees had slow water leakage. Replaced them with equal parts from Rain Bird who (I was surprised to see this as other Orbit drip irrigation parts (like the original Apollo 8 DripMaster 6700 manifold) have worked well for me so far. Have other users seen this? Maybe they work better with Orbit 1 4 inch tube ?
