Compression Tester Replacement VALVE CORES pack of 3 for gas engine testers New

Description

Compression Tester Replacement VALVE CORE (S) pack of 3 for gas engine testers
New high quality valve cores for the inlet side of gas engine compression testers
these are the low pressure opening valve cores that are needed to get a correct pressure readings on your handheld or screw in type gasoline compression tester. Regular tire or ac valve cores require higher opening pressure and give inaccurate (low or zero) readings.
Because the correct valve cores have such a low opening pressure they seem to go bad often (or get stuff stuck in them) and thats when the gauge wont hold pressure or bounces up and down when trying to test an engines compression.
FOR GAS ENGINE TESTERS ONLY NOT FOR DIESEL TESTERS
not for the release valve at the head of the tester you can use a regular tire valve core for that , these are for the inlet end that screws or push's into the cylinder.    installs with a regular valve core tool
pack of 3 (bulk pack) so you have spares , I accept returns but sorry no warranty on these valve cores. Maximum working pressure 300 psi.
