Meet the Apollo PEX-A 1 in Expansion PEX to 1 in Sweat Brass Male Adapter—a precise, durable bridge between modern PEX-A networks and traditional copper piping. Designed for reliability in hot water and radiant heating applications, this 1" brass adapter is built to perform under real-world conditions.
Key advantages you’ll notice in everyday projects:
-
Dual-end compatibility: one end accepts expansion PEX-A, the other end provides a sweat connection to 1" copper/brass pipe, enabling seamless integration of PEX-A with existing metal piping.
-
Lead-free brass construction: ensures safe potable-water performance and long-lasting durability in domestic plumbing systems.
-
ANSI certified: certified performance that aligns with industry standards and Apollo’s PEX-A ecosystem for consistent results.
-
Robust pressure and temperature tolerance: rated up to 200 psi and up to 200°F, supporting demanding hot-water and heating installations without compromising seal integrity.
-
Compact, reliable design: a single-piece brass body keeps fittings tidy in tight spaces and reduces potential leak points compared with multi-piece assemblies.
-
Practical packaging: bagged 1-piece package ensures you receive a ready-to-install connection with minimal waste.
How it works
Use this adapter to connect an Apollo PEX-A expansion line to a copper or brass pipe via a sweat joint. The expansive PEX-A end is expanded with your PEX expansion tool, then slid over the adapter’s expansion end and seated. The opposite end is soldered (sweat) onto a 1" copper/brass pipe with standard flux and solder. Once cooled, the joint forms a secure, code-compliant connection designed for durable service.
Ideal use cases
- Retrofits where you’re tying a modern PEX-A loop into an existing copper distribution network.
- New installations that combine PEX-A radiant heating or hot-water loops with traditional piping routes.
- Any 1" PEX-A to 1" sweat copper/brass transition where a reliable, lead-free brass connection is essential.
Why choose this Apollo adapter over other options? It delivers a corrosion-resistant brass body, proven ANSI certification, and a reliable expansion-to-sweat connection designed to endure the temperature and pressure demands of household plumbing. With its 1" ends and a focus on PEX-A compatibility, it provides a straightforward, long-lasting solution that simplifies complex piping layouts and minimizes potential leak points.
Compatible with Apollo PEX-A systems and standard 1" copper piping, this adapter is a practical, code-friendly choice for installers and DIYers who demand precision, durability, and ease of use in every connection.
