Best way to seal heater core pipe off water pump.
So, I have a brand new water pump and metal hose section for heater core. What is the best way to seal the threads? Also, if I turn it til tight, it’s not aligned. If I back it off to align, it’s not tight. Should I’d use some Teflon tape?

Also used it for the old temp sensor in the new thermostat housing too.

Damn. Already got it back together with just tape. We’ll see. My sensor only has tape, and it has not leaked at all.

Tapered threads such as the pipe fitting you're dealing with are designed to be turned past snug to the required orientation. They typically require thread tape or paste to seal properly, by design. Use thread tape/compound on every tapered thread you encounter.

They're all good options done properly.

I have used tape and liquid thread sealant over the years but have started using Rectorseal T plus 2 thread sealant. I had a fitting that just wouldn’t stop weeping and a plumber friend suggested this and it worked the first try…great stuff.
