Jack's Formula 327 Lube is the right stuff to use lubricating pool gaskets and o-rings!
Jack's 327 is the one to use without harming your pool gaskets and o-rings. Don't use Vaseline, baby oil or other petroleum and mineral based products. They may lubricate, but they will be absorbed into the o-ring and cause the o-rings to swell and grow in size, then you'll need to replace them again and again. Jacks formula 327 O-ring lubricants are equal to none. This is great for quick fixes! Lasting lubrication and protection! 1 oz tube.
