This compression adapter is a game changer for engine testing. As my tests showed it's easy to use and provides accurate readings. The construction is durable and can withstand heavy use. THE only downside is that it may not fit all vehicle models, so make sure to check compatibility before purchasing. Overall, highly recommended for any DIY mechanic!
Pros
Easy to install and use with a variety of vehicles.
Cons
Requires additional tools to function properly and can be expensive for occasional use.
Not sure why they are so hard to find. Needed one but couldn't find one locally. Works with compression testers with 14mm nipples or male adapters. Additional benefit through hose extension. I was able to mount the sensor on the windshield and watch it while rotating it in the cockpit.
