Dave H M: Reguiar so called plumbers grease is a petroleum product and will swell and eventually destroy any rubber products. One should instead use silicone grease which will not react with rubber. Guess how I know? It's a shame that plumbers grease uses that name because it can be very misleading. Used plumbers grease for years. on the dump valves on my rv and constantly fought them cause the seals had swelled and made the valves hard to pull. At one point I pulled the handle so hard the seal popped out of place and I had a real mess draining onto the black top at a Walmart store in New Mexico.
