I would like to buy two fittings for a project. I only need one of each, so do not want to buy packages of them as found on Amazons. I need a 3/4" y fitting barbed, to split one flow into two streams and I need a 3/4" barb to 1/2 " barb to connect one stream to a device that only fit 1/2 hose. Thank you for your time.
