Apollo makes PEX brass fittings and crimping tools for contractors working with cross-linked polyethylene pipe systems. Their product line centers on lead-free DZR (dezincification resistant) brass components rated for 200°F and 200 PSI — specifications that matter when you’re running hydronic heating loops or dealing with Montana’s mineral-rich water.
The PEX Brass Fitting System
Apollo’s core offering includes couplers, elbows, tees, and ball valves, all manufactured from lead-free dezincification resistant brass. Every fitting in the line shares the same ratings: 200°F maximum temperature and 200 PSI maximum pressure. That consistency matters when you’re spec’ing a whole system.
The DZR brass construction addresses a real problem in areas with aggressive water chemistry. Standard brass can lose zinc content over time, leaving behind porous copper that fails. DZR brass resists this dezincification process, extending fitting life in corrosive conditions.
All fittings work with standard PEX-B tubing using barb connections secured by crimp rings, crimp sleeves, or pinch clamps. The fittings meet ASTM F1807 standards for metal insert fittings, while NSF-pw Annex G certification covers potable water applications.
| Component | Size | Connection Type | Max Temp | Max Pressure |
|---|---|---|---|---|
| Coupler | 1/2” x 1/2” | Barb/Crimp | 200°F | 200 PSI |
| Elbow | 1/2” x 1/2” | Barb/Crimp | 200°F | 200 PSI |
| Tee | 1/2” x 1/2” x 1/2” | Barb/Crimp | 200°F | 200 PSI |
| Ball Valve | 1/2” | Barb/Crimp | 200°F | 200 PSI |
The 10-pack format on most fittings makes sense for contractors. You’re not buying singles at markup — you’re stocking the truck with what you’ll actually use on a job.
Crimp Ring System and Installation Tools
Apollo’s copper crimp rings come in annealed copper rated for 160 PSI at 73°F or 100 PSI at 180°F. Those pressure deratings at temperature are standard across the industry — hot water weakens the connection.
The rings meet the full compliance stack: ASTM F1807, F876, F877, CSA B137.5, and NSF/ANSI 61 and 14. That’s every standard a plumbing inspector might ask about.
The real tool worth discussing is Apollo’s multi-head crimp tool that handles 3/8” through 1” sizes with 100 pounds of crimping force. The kit includes four interchangeable crimp heads, adjustment wrench, and a Go/No-Go gauge. That gauge matters — it’s the difference between a callback and a proper installation.
Ball Valve Design Features
Apollo’s PEX ball valves use quarter-turn lever operation with Teflon seats and blow-out proof stem design. The blow-out proof stem prevents the handle assembly from shooting off under pressure if someone loosens the packing nut while the system’s live.
These valves match the 200 PSI/200°F ratings of the fitting line and use the same lead-free brass construction. Quarter-turn operation beats multi-turn gate valves for shutoff speed, and Teflon seats won’t corrode or bind like metal-on-metal designs.
The consistent pressure ratings across the entire product line eliminate weak points. When every component handles 200 PSI, you’re not creating failure points by mixing ratings.
The Bottom Line
Apollo delivers a complete PEX brass system that handles Montana conditions. The 200°F rating covers hydronic heating applications. DZR brass resists corrosion from mineral-laden water. Lead-free construction meets current codes.
For contractors already invested in crimp-style PEX installation, Apollo provides professional-grade components without premium pricing. The multi-head crimp tool with Go/No-Go gauge shows they understand what matters for reliable installations.
Skip Apollo if you’re committed to expansion-style PEX systems or need larger than 1” fittings. But for standard residential and light commercial PEX work, their brass fitting line delivers the durability and consistency that prevents callbacks.
Frequently Asked Questions
Q: What’s the difference between DZR brass and standard brass fittings?
DZR (dezincification resistant) brass prevents the zinc from leaching out of the alloy over time. Standard brass can lose zinc in aggressive water conditions, leaving porous copper that eventually fails. The DZR treatment provides long-term reliability and corrosion resistance, especially important in areas with low pH or high mineral content water.
Q: Can I use Apollo brass fittings with PEX-A tubing?
Apollo fittings are specifically designed for PEX-B tubing using barb connections with crimp rings, sleeves, or clamps. While the barb design might physically fit PEX-A, these fittings aren’t rated for expansion-style connections. Stick with the intended PEX-B application for warranty coverage.
Q: What pressure rating should I use for hot water systems?
Apollo crimp rings derate from 160 PSI at 73°F down to 100 PSI at 180°F. The brass fittings themselves maintain their 200 PSI rating up to 200°F. Design your system around the lower crimp ring rating for hot water applications.
Q: Do Apollo fittings require special crimping tools?
Apollo’s multi-head crimp tool handles all sizes from 3/8” to 1” with 100 pounds of crimping force and includes the necessary Go/No-Go gauge for verification. You can use other ASTM F1807-compliant crimp tools, but having the gauge to verify proper crimps prevents leaks.
