3/4 inch Brass 90 Degree Insert Elbow Insert x Male

3/4 Inch Brass 90-Degree Insert Elbow – Insert x MPT for PE Tubing Connections

The 3/4 inch Brass 90-Degree Insert Elbow is a precision-formed plumbing component designed to facilitate directional transitions between polyethylene (PE) tubing and standard threaded fittings. With one barbed insert end and one male pipe thread (MPT) end, it enables a secure 90-degree turn in cold water distribution systems using flexible tubing, particularly in confined installation zones.

Manufactured from lead-free brass, this elbow delivers corrosion resistance and pressure handling appropriate for underground, in-wall, and utility installations. The dual-connection format supports hybrid systems where PE tubing must be joined to metallic or threaded components.

Application and Performance Characteristics

• ✅ Insert x Male NPT Configuration – Allows direct transition from PE pipe to threaded fittings in control valves, manifolds, or service entries.
• ✅ Lead-Free Brass Construction – Complies with NSF/ANSI 372 for potable water use and corrosion resistance in wet or buried environments.
• ✅ Barbed Insert End – Designed for polyethylene tubing connection using stainless steel clamps or crimp rings per ASTM D2104 and D2737 standards.
• ✅ Threaded End – Machined to ANSI/ASME B1.20.1 NPT specifications for secure mechanical sealing in compatible female-threaded ports.

Installation Notes

For optimal performance, the insert end should be secured with an approved clamp or crimp system compatible with PE tubing and local code. The threaded end requires PTFE tape or a certified pipe joint compound to ensure leak resistance. Ensure alignment to avoid cross-threading or stress on the fitting body.

Typical Use Cases

This 90-degree elbow is frequently used in irrigation manifolds, municipal water service lines, underground distribution systems, and applications requiring a turn from flexible pipe to metal or PVC threaded connections. Its compact form allows for installation in tight access areas such as meter pits, control boxes, and foundation penetrations.

Material and Code Compliance

Brass insert fittings remain a standard for polyethylene tubing connections due to their mechanical strength, longevity, and resistance to dezincification. This component meets federal requirements for lead-free plumbing and is approved for potable water systems under NSF/ANSI 61 and 372.
