Why This Product Matters

When you’re up on a rooftop in 40-degree heat, you don’t want to be mucking around with dodgy piercing valves or jerry-rigged ports. A proper copper access tee gives you a permanent, sealed service point that holds up to repeated connection cycles. One Sydney contractor told us they swapped to these tees after a spate of leaks from old service taps—no worries since, and fewer nuisance call-backs.

Pro Tip

Before brazing, remove the valve core and cap, wrap the body with a wet rag, and purge nitrogen through the line to prevent scale. After cool-down, reinstall the core, tighten with the wrench cap, then pressure test and soap to confirm a clean seal.
