Lead-free brass adapter (NFPA Expo)
Easier to install and more cost-effective compared with traditional stainless-steel fire sprinkler adapters, the Uponor ProPEX lead-free brass fire sprinkler adapter meets state lead-level legislation and conforms to NSF Annex G for lead-free plumbing requirements (i.e., no more than 0.25% weighted average lead content on wetted surfaces).
The new adapter provides easier installation on a variety of surfaces, offering flexible preassembly and mounting options with no blocking required. Available in ¾” and 1” tees, each assembly requires a mounting bracket and a push-on locking nut. The adapter also features Uponor’s cold-expansion ProPEX fitting system for durable and reliable connections without the need for torches, glues, solvents or gauges.
