| Is there a difference between the white plastic fittings and the black plastic fittings ? This is to be used for liquid fertilizer plumbing 2 inch. The existing fittings are 30 years old and black. I am putting new hose on . Fittings look good no leaks should i reuse them ? Plan on keeping the planter. Only use the liquid for about 160 acres every year. I have not priced new fittings . I am leaning towards replacing the fittings . What is a good thread sealer ? Thanks | |
