# Gasket

> A gasket is a thin seal between two fixed surfaces that stops oil, coolant, fuel or gas from leaking out of the joint.

- **Also known as:** Conta takımı, Üst takım conta, Gasket

The material depends on where it is used: paper or fibre (covers), multi-layer steel (cylinder head gasket), rubber (O-rings, cover seals) and liquid gasket. For engine work, gaskets are usually sold **as sets**: a top-end set (cylinder and head) and a bottom-end set (crankcase and covers).

- Never reuse a gasket; once compressed it will not seal properly a second time.
- Clean the faces and tighten the bolts in the sequence and to the torque in the manual.
- A leaking head gasket causes compression loss; a leaking exhaust gasket causes popping.
