Piston Ring Compressor Set 73-111mm 7pc Adjustable

A 7-piece piston ring compressor set for fitting piston rings into bores from 73mm to 111mm. Supplied with ratchet compressor pliers and six adjustable swivel bands, it allows the rings to be compressed in small increments for more controlled installation.

Used for engine work, rebuilds and servicing jobs where pistons need to be installed without damaging the rings, this type of set is useful for garage work, workshop use and vehicle maintenance. It helps when working across different engine sizes, as the included bands cover a spread of common bore ranges rather than relying on a single fixed compressor. For mechanics, engine builders and experienced DIY users, it gives a more manageable way to fit piston rings during repair and reassembly work.

The ratchet pliers are made to tighten the bands gradually, which helps with steady adjustment while fitting. Each band swivels, making the set easier to use at different angles depending on access around the block or bench setup. With six separate band sizes included, it covers 73-79mm, 79-86mm, 86-92mm, 92-98mm, 98-105mm and 105-111mm, helping cover a useful range for regular engine maintenance and rebuild work.
