3/4 inch Brass Pack Joint Adapter Lead-Free Copper x Male

3/4 inch Lead-Free Pack Joint Adapter – Compression Transition for CTS to MIP Connections

The 3/4 inch Lead-Free Pack Joint Adapter is engineered for joining copper, CPVC, or PEX tubing to male iron pipe threads in water service applications. This compression-style fitting uses a brass body and compression nut with a sealing gasket to form a reliable mechanical connection without the need for soldering or heat.

Designed for underground and above-ground potable water installations, this adapter accommodates 3/4 inch CTS (copper tube size) pipe on the pack joint end and transitions to a 3/4 inch MIP (male iron pipe) thread. It is commonly used at water meter inlets/outlets, curb stop transitions, or where municipal service lines interface with threaded plumbing components.

Product Features

• ✅ Lead-Free Brass Construction – Meets federal and state requirements for use in potable water systems (NSF/ANSI 372 compliant).
• ✅ Pack Joint Design – Allows a mechanical seal using a compression nut and gasket to secure CTS tubing without flame or adhesives.
• ✅ Threaded Outlet – 3/4 inch MIP outlet for direct connection to threaded valves, fittings, or service piping.
• ✅ Corrosion-Resistant Components – Engineered to resist galvanic corrosion and environmental degradation in service line conditions.

Specifications

• Size: 3/4 inch CTS x 3/4 inch MIP
• Material: Lead-free brass (typically alloy C69300 or equivalent)
• Seal Type: Compression gasket (EPDM or Buna-N)
• Connection Type: Pack joint x Male Iron Pipe Thread (MIP)
• Compliance: NSF/ANSI 61 & 372 certified; AWWA C800 compliant design (verify with specific manufacturer)

Installation Guidelines

Cut tubing square and remove burrs before inserting into the adapter body. Slide the nut and gasket over the tubing, insert fully into the fitting, and hand-tighten the nut. Use an appropriate wrench to torque to manufacturer specification. Threaded connections should be sealed with PTFE tape or thread sealant to ensure watertight installation. Support piping as required by code.

Application Uses

Commonly installed at transition points in municipal water service lines, meter yokes, and distribution manifolds. Also applicable in residential and light commercial water distribution systems where CTS tubing transitions to threaded valves or pipe sections.

Code Compliance Note

Lead-free pack joint fittings are mandatory for use in potable water systems across all U.S. jurisdictions. Ensure proper installation torque and pipe alignment to maintain long-term joint integrity.

The 3/4 inch Lead-Free Pack Joint Adapter provides a code-compliant, field-ready solution for transitioning between copper tube size piping and threaded system components. Its mechanical design simplifies service connections while supporting leak-resistant performance in both new construction and replacement scenarios.
