Here at Cromwell, we have a wide range of piston ring, valve & grinding tools from our trusted own brand Kennedy® as well as national leading brands such as Sykes-Pickavant.

Why piston ring, valve & grinding tools?

To ensure optimum performance of your engine, it's important to periodically check and the valves in your cylinders. Whilst this doesn't need to be a laborious or particularly regular task for the hobbyist or casual driver, for automotive technicians, mechanics or engineers, this is a far more frequent task. Valves should be checked and re-ground if the sealing faces aren't completely clean and flush in their seat, to ensure no gas is allowed to leak through. Piston ring, valve and grinding tools are designed to make this task and similar others easier.

Piston ring, valve & grinding tool types

When performing general maintenance or complete refurbishment of your engine, it's vital to have the right tool to hand. When it comes to piston rings and valves, we have a host of tools that will ensure you keep your vehicle running smoothly. There are multiple types of tools that can assist you in your task. The most common are listed and described below for your ease.

• Piston ring compressors   -   Designed for holding piston rings in place once removed from the cylinder, a piston ring compressor works by gently compressing piston rings into position whilst also reducing the ris of damage to components during installation.

• Valve spring compressors   -   Suited for removing and placing valve springs from cylinder heads, valve spring compressors are invaluable when working on engines.

• Valve grinding tools   -   Valves should be ground or lapped to ensure a tight seal. Old valves will also sometimes need to be removed and cleaned/ground down and carbon deposits removed. Common valve grinding tools include suction valve grinders which aid in the removal of valves which is paired with a valve grinding paste when grinding valves.

• Valve seal ring pliers   -   To aid in the removal of valve stem seals and lower valve spring guides in restricted areas above the cylinder head, valve seal ring pliers are aesthetically similar to regular pliers.

• Piston ring pliers   -   As they sound, piston ring pliers are designed to enable fast installation and removal of piston rings.
