Mueller Streamline acp02715 Brass Push Fitting 90 Elbow

Product Description

The MUELLER STREAMLINE acp02715 is a 1/4-inch O.D. brass push-fit 90-degree elbow designed for permanent, tool-free, and flame-free connections in refrigerant piping systems. It uses proprietary BackBite Grip Ring Technology along with a double O-ring seal to create a reliable joint rated to 700 psi continuous operating pressure. The fitting is manufactured in the USA and backed by a 10-year warranty. Licensed HVAC technicians and refrigeration mechanics install this fitting during air conditioning system assembly, service, and repair work where open-flame brazing is not practical or permitted.

This fitting is suited for residential and commercial air conditioning, heat pump, mini-split, VRF, and VRV system installations and repairs. It also carries approval for non-potable water and technical or inert gas applications. The push-fit design is available across a range of O.D. sizes from 1/4 inch to 7/8 inch, making it part of a broader system of compatible Streamline refrigerant push fittings. It is approved for use with hard and soft-tempered copper tubing.

Installation Notes

This fitting is installed by licensed HVAC technicians and refrigeration mechanics. Always recover refrigerant and depressurize the system before cutting into existing refrigerant lines. Ensure copper tubing ends are cut cleanly and deburred before inserting into the fitting to achieve a proper seal. Because the BackBite Grip Ring creates a permanent, non-removable connection, verify routing and fit before pushing the tubing fully home. Follow applicable mechanical codes and manufacturer guidelines for refrigerant system work.
