You also might be able to get an adjustable one (that has a worm screw clamp around a taped compressor with a split in it). They work pretty good. Summit has a Total Seal brand one in stock, TSR-RC4345-4455, $55.95. Brian

I just tighten them up until it measures dead on the bore size I'm working with and it'll work just as good as one of the fixed ones. These style compressors will make you throw away the old flimsy metal ones w/ the hose clamp.

[/quote] I've worn out several different type ring compressors before starting to buy and use the fix tapered ones, sometimes I make bad decisions on tools I should have bought them years ago Last edited by Cab_Burge; 01/27/22 09:02 PM.
