Keno Posted July 17, 2019 Report Share Posted July 17, 2019 TB05EMA are NGW 8636 LB05EP are NGW 8020 LB05EZ are NGW 8744 LB05EZA are NGW 8769 I like the TB05EMA ones, they are what I use on Jetskis and are water proof, but cost more. The LB series are phenolic resin instead of rubber. The "Z" designation may mean vibration resistance or waterproof, The "A" I have no idea. I have used the LB05EP and would be my last choice as it caused nut wear on my spark plugs and didn't seal well. Quote Link to comment Share on other sites More sharing options...
