Midland Industries 9631212LF Pack Joint Adapter 3/4 in Cts X Pep

Product Description

The MIDLAND INDUSTRIES 9631212LF is a lead-free bronze pack joint adapter designed to connect copper tubing (CTS) to polyethylene pipe (PEP) in potable water and plumbing systems. Both ends are 3/4 inch pack joint connections, allowing a tool-free, compression-style assembly without soldering or special fittings. The lead-free bronze construction meets safe drinking water requirements, making it suitable for use in residential and light commercial water service lines. Plumbers and water service technicians install this fitting where a CTS copper run transitions to a PEP polyethylene line, a common configuration in service entrances and underground water supply applications.

This adapter is used in residential and light commercial plumbing where copper tubing transitions to polyethylene pipe, such as water service laterals, irrigation feed lines, and underground supply runs. Pack joint fittings are favored in these applications because they grip the tubing mechanically without heat or adhesive, speeding up installation in tight or below-grade conditions. The fitting works with copper tubing on one side and polyethylene pipe on the other, both at 3/4 inch nominal size.

Compatibility

Designed for use with copper tubing (CTS) and polyethylene pipe (PEP) at 3/4 inch nominal size in residential and light commercial plumbing water service applications.

Installation Notes

This fitting is installed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve line pressure before disassembling or installing any compression or pack joint fitting. Ensure tubing ends are cut square and deburred before insertion to achieve a proper seal. Do not over-torque the pack joint nut, as this can damage the internal gripper ring and compromise the connection.
