Frequently Asked Questions

AI
Rubber gaskets, often made of nitrile, are excellent for oil and water resistance in standard plumbing. Silicone gaskets generally offer better heat resistance and flexibility, making them ideal for hot water pipes.
The most reliable method is to take the old gasket to a hardware store for comparison. If buying a kit, look for assortment sets that include a wide range of inner diameters (ID) and thicknesses.
Generally, no. Once a gasket has been compressed and exposed to wear or chemical degradation, it loses its elasticity. Replacing it with a new one is the only way to guarantee a leak-free seal.
