Do you seal a gasket before you install it?
In the past, it was not uncommon to coat a gasket with sealers or adhesives before installing it; today, Fel-Pro offers many gasket designs with advanced leak sealing technologies built directly into the gasket. With these modern gaskets, RTV or other sealers can actually hinder the gasket’s ability to form a reliable seal, causing leaks.
What should I use instead of a plumber’s gasket?
The faucet will typically come with a rubber or plastic gasket, or a trim ring, that you will need to place over the faucet holes in the sink. Sometimes, you may be directed to use plumber’s putty instead of a gasket. In this case, follow the instructions on the plumber’s putty.
When is the best time to reassemble a gasket maker?
Waiting for the gasket maker to partially dry before reassembling. Many mechanics like to wait for the gasket material to ‘skin over’ before reassembling. But in most cases, gasket makers work best when assembled immediately, while the material is still wet (solvent-based gasket makers / sealants are an exception to this rule).
What should bead thickness be for gasket maker?
Knowing the right amount to apply takes some experience, but a bead thickness of around 1/8” is a good place to start. The bead of gasket maker or flange sealant that you apply will spread out to a very thin layer when you tighten up your assembly, so you don’t need to apply a lot of product to get the ideal seal.

Which is the best guideline for gasket installation?
ASME PCC-1 is a post-construction guideline for pressure boundary bolted flange joint assemblies, and the bulk of gasket manufacturers derive their installation procedures from this guideline.
How long does it take for gasket to relax after installation?
It has been well documented that relaxation in a bolted joint flange assembly occurs within the first four to 24 hours after initial installation due to gasket creep, and bolt and flange relaxation.
