Review on 💧 Superior Loc Line Coolant Component: Acetal Copolymer for Efficient Cooling by Issac Smart

I bought these to replace the low point drain plugs on my RV. According to the packaging they are only rated for 20psi, not 100psi as stated in the product description. Since the water pressure in an RV is about 40psi, I'm not sure they can handle higher pressures without leaking. I will install them in about two weeks and check my review after the trial period.
