Simple copper gaskets-good price compared to the other leading brand.
For pennies a gasket, box of 100 makes sense. Well made, change one every time a plug is removed for any reason, including engine borescope. Really great value for simple plug maintenance.
After I switched to Tempest Fine wire plugs, I followed suit and switched to these U674 well formed Tempest Gaskets. Also, I use new ones each time I reinstall my plugs.
Price and quantity beats other suppliers.
Use new gasket each time I pull spark plug.

You will need to use 18mm gaskets for REM38E plugs.
The only difference between the two is that one is made by Tempest and the other is by Champion.
These are the correct copper gaskets for your plug. Our part # is 07-01798, Tempest manufacturing part # is UM674PK.
URHB32E uses 18mm gaskets. So you can order this part # 07-01798, which is a 100 pack, or you can order part # 07-00877, which are sold individually.
Yes.
Yes, the B in RHB32E designates 18mm. These will work on RHB32E Champion plugs.
Both the UREM38S and the UREM37BY are 18mm spark plugs. This part # 07-01798, is the correct size for these plugs.
