Mueller Industries rp10141 Acr Copper Press Coupling

Product Description

The MUELLER INDUSTRIES rp10141 is a 1/4-inch OD ACR copper press coupling with a staked stop, designed for refrigeration and air conditioning line connections. The press-fit connection eliminates open-flame brazing, reducing installation time and fire risk in the field. Built from copper, this coupling handles system pressures up to 700 psi and operates across a temperature range of -40 degrees F to 250 degrees F. HVAC and refrigeration technicians use this fitting where a reliable, leak-tested mechanical joint is required on ACR copper tubing.

This coupling is suited for residential and light commercial HVAC and refrigeration systems that use 1/4-inch OD ACR copper tubing. The staked stop ensures consistent insertion depth during assembly, reducing the chance of incomplete engagement. It is a common choice for field repairs, new installations, and retrofit work where torch-free joining is preferred or required by site conditions.

Key Features

• Press-fit connection eliminates open-flame brazing at the joint
• Staked stop provides positive, repeatable insertion depth
• Rated to 700 psi maximum working pressure
• Operating temperature range: -40 degrees F to 250 degrees F
• Copper construction for compatibility with ACR refrigerant lines

Compatibility

Designed as an OEM-style press coupling for 1/4-inch OD ACR copper refrigerant tubing used in residential and light commercial HVAC and refrigeration systems.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician using a press tool approved for ACR copper fittings. Recover and isolate refrigerant from the system before cutting or joining any refrigerant line, in compliance with EPA Section 608 regulations. Verify that tubing ends are cut square, deburred, and fully seated to the staked stop before pressing. Do not use this fitting on systems exceeding its rated pressure or temperature limits.
