Apollo 3/4 in Brass PEX 90 Elbow 25-Pack

This 25-pack of Apollo brass PEX barb 90-degree elbows is built for potable water distribution and hydronic heating loops. Each fitting accepts 3/4 in tubing and joins securely with copper crimp rings, stainless steel pinch clamps or stainless steel crimp sleeves. The brass construction resists corrosion in continuous water contact. The jar keeps the fittings organised on the job site.

Installation uses crimp, pinch or sleeve clamps

No proprietary tools are required; standard PEX crimp or clamp tools engage the barb profile. The barbed end seats fully when the tubing is pushed to the shoulder, giving a tactile stop. A common error is leaving the clamp too far back on the barb, which can leak under pressure. Another issue is mixing clamp types on the same joint, which prevents a uniform seal. The fittings are lead-bearing per California Proposition 65, so wash hands after handling.

Sustained pressure holds without creep

The brass body maintains dimensional stability under constant system pressure and thermal cycling in heating applications. Unlike plastic elbows, the metal barbs do not relax over time, so clamp tension remains consistent. The 90-degree radius keeps flow restriction low during continuous circulation. The jar packaging protects threads and barbs from damage during long-term storage.

Questions about this item

How can I confirm the Apollo APXE3425JR 90-degree elbows are seated correctly after crimping?

After crimping each brass PEX barb with a calibrated tool, run a pressure test on the potable water or hydronic heating system; leak-free joints at working pressure confirm the 25 fittings are installed as intended.

The jar holds 25 brass elbows — what else must I purchase to complete the connections?

Copper crimp rings, stainless steel pinch clamps or stainless steel crimp sleeves are required to secure the 3/4 in. PEX tubing into the barbs; all three fastener types are sold separately.

This is the only 3/4 in. 90-degree elbow jar listed — how do I know it matches my tubing size?

The fitting is sized for 3/4 in. PEX tubing; verify your tubing carries the same 3/4 in. designation before using the 25-pack in a potable water or hydronic heating system.
