Introducing the Apollo PEX-A 3/4 in Expansion PEX to 3/4 in Barb Brass 90 Degree Elbow—the reliable brass elbow that cleanly converts a 3/4" Expansion PEX run to a 3/4" barb connection in tight spaces. Built from lead-free brass, it’s a durable, code-compliant solution for potable-water installations that demand longevity and performance.
-
Lead-free brass construction delivers corrosion resistance and safe, potable-water performance for years to come.
-
Two distinct connection ends—one end is Expansion PEX for seamless integration with Apollo PEX-A systems, the other end is a 3/4" barb designed to accept standard tubing secured with a clamp.
-
90-degree elbow geometry minimizes space while maintaining smooth flow paths, making it ideal for under-sink, behind appliances, or tight retrofit projects.
-
Rated for demanding conditions up to 200 psi and 200°F, suitable for most residential hot and cold-water applications.
-
ANSI certified to ensure reliable, performance-backed installation you can trust on every job.
- One-piece, robust design reduces potential leak points and simplifies care during future maintenance or upgrades.
Why this elbow fits your project
If you’re integrating a PEX-A expansion system with traditional barb fittings, this elbow provides a clean, compact transition that preserves flow efficiency and minimizes turbulence at bends. Its brass body resists scale buildup and corrosion, a practical choice for kitchens, baths, laundry rooms, and mechanical spaces where space is at a premium.
Ideal use cases
- Connecting a PEX-A expansion line to a 3/4" barb hose or tubing in tight spaces behind sinks or appliances.
- Retrofits where a 90-degree change of direction is needed between PEX expansion runs and barb-style connections.
- Riser or wall-embedded plumbing runs that require a compact, durable transition fitting.
Installation at a glance
- Cut and deburr the 3/4" Expansion PEX end to the required length.
- Use the appropriate Apollo PEX-A expansion tool to fit the Expansion PEX end onto the Elbow’s expansion connection, ensuring a secure, leak-free seal.
- Slide or attach a 3/4" barb-compatible hose or tubing onto the barb end and secure with a clamp suitable for your system.
- Check for alignment, then slowly restore water pressure and inspect for leaks at all connections.
Embrace a dependable, code-approved transition that keeps your piping clean, efficient, and ready for years of use. The Apollo PEX-A 3/4 in Expansion PEX to 3/4 in Barb Brass 90 Degree Elbow is the practical choice for professionals and DIY enthusiasts who value precision, durability, and easy integration with PEX-A systems.
