You asked for it so we made it happen. Many of you have been wanting to know what we use for high temp thread sealant (when we don't want to use the permanent epoxy). We don't like thread tape or anything with Teflon in it.
This small tube of sealant by Permatex with meet most your needs of sealing NPT tapered threads on aftermarket pumps, filters, hose fittings, etc. Very effective sealant that will allow you to easily remove the fitting if you need to.
