Just what the doctor ordered
There are other options for 30psi, 178000 BTU boiler relief valves. They all cost more b/c they include various bells and whistles. This one seems to strike the right balance between the quality and the price. It's been on for about half a year and has not leaked (knocking on wood) yet. I expect it to continue this way for at least 20 years. As long as it does, this will stay a 5-star review.

No Issues
No issues. Exact replacement of existing relief valve on furnace. Works well (no leaks) with teflon tape - no need for pipe dope. Word of advice... Unless your furnace is pristine, I wouldn't flip the relief valve lever after installation to test the valve. Any crud in your furnace water might work its way into the valve and cause the valve to leak, and then you'd have to flush the valve or clean it. I'm not saying to never test the valve, just leave it for your yearly maintenance.
