Nice adapter

This item arrived as advertised. The adapter works with my compression tester. It is heavy duty, made of steel and coated with copper, to make it look like brass, but it isn't. No problems noted at this time.As with all my reviews when I have only confirmed receipt of item, unboxed and inspected it to make sure the item is as advertised, I will update the review if any issues are noted upon installation, or if it fails to meet expectations.

It fits as you'd expect. Made testing compression easy. Sealed up well. Great adapter to have.

The internal thread of this item didn’t fit any known fitting. Contact with the supplier was attempted three times by email asking what the threads were. There was no reply. The thread to conduct compression test for aircraft require a 1/4 NPT pipe thread for an air supply connection. Therefore this item could not be used.

Threaded portion not long enough and body too wide to fit in plug well. I need a longer thread.

I use this in the equipment I have with 10mm spark plugs, most compression guages are 14mm, this will adapt, this is best used for leak down and not compression.

I bought these to make low clearance adapters for a compression test on an engine with headers. They worked well, but a hex in place of the knurl would work better.

My M12 adaptor for my cylinder leakdown tester went AWOL. This adaptor screwed right on and didn't cost tool truck prices! Perfect!
