What is the difference between a valve seal and a valve seat?
A valve seal is a type of mechanical seal that is used to prevent the leakage of fluid or gas from a valve. It does this by creating a tight seal between the moving parts of the valve and the stationary parts. A valve seat is the part of a valve against which the seal rests.

What is a seat seal?
Seat Seals
Like many non-elastomer seals, these are often “backed” with an elastomer o-ring to aid in movement and support sealing. In butterfly valves the elastomer or other material becomes an integral part of the pipeline, affecting a seal when the disc is rotated into the closed position.

How to stop gate valve from leaking?
For a minor leak at the valve stem, try tightening the packing nut first. This simple step often compresses the old packing enough to seal it again. Pick an adjustable wrench that fits the packing nut snugly. This is the nut right below the valve handle.Sep 23, 2025
