This air compressor head gasket set is a 3 piece kit of plastic valve plate gaskets and washers for the cylinder head and base of a piston compressor pump. It is sold in five sizes, 51 Type, 65 Type, 80 Type, 90 Type and 95 Type, so the set can be matched to the pump being rebuilt by measuring the hole spacing.
Features and benefits:
- 3 piece set per order - the gaskets and washers needed for one head and base rebuild come together in one pack
- Five sizes to choose from, 51, 65, 80, 90 and 95 Type - pick the one that matches your pump
- Hole spacing is published for each size, for example 46mm on the 51 Type round gasket and 70mm on its square gasket - measure your old gasket and compare before ordering
- Mix of round and square gaskets in the set - covers the sealing faces between head, valve plate and base
- Plastic construction - simple replacement for worn or leaking seals when servicing a compressor pump
- Flat gasket and washer design - quick to fit during a pump strip down
Applications:
- Rebuilding a worn piston air compressor pump
- Replacing a leaking cylinder head or valve plate seal
- Workshop and garage compressor servicing
- Keeping spare gaskets on the shelf for planned maintenance
In the box:
3 x valve plate gaskets and washers (one set).
Note: Sizes are matched by hole spacing, so measure between the bolt holes on your old gasket before choosing a type. Depressurise the compressor and isolate it from power before stripping the pump. Colours may vary slightly from the pictures.

A: It seals the joints between the cylinder head, valve plate and base so compressed air stays in the pump and does not leak out. A worn or damaged gasket is a common reason for lost pressure after years of use.. Q: How do I know which size gasket set my compressor needs? A: Measure the distance between the bolt holes on your old gasket and compare it with the published hole spacing for each type. For example the 80 Type round gasket measures 72mm and the 90 Type measures 81mm.. Q: How many pieces are in the set? A: Each set contains 3 valve plate gaskets and washers. The option you choose sets the size, 51, 65, 80, 90 or 95 Type.. Q: Can I use this when rebuilding a compressor pump? A: Yes, the gaskets are made to be fitted when the head and valve plate are removed for a rebuild. Check the size against your pump before fitting..
