Macomb Group Approved 537153 3/4 in Pp 45 Deg Elbow

Product Description

The MACOMB GROUP APPROVED 537153 is a 45-degree elbow fitting designed for high purity piping systems where contamination control is critical. Manufactured from polypropylene meeting ASTM D4101, this fitting connects via socket fusion, creating a strong, leak-free joint without adhesives or solvents. It is rated for service up to 150 psi at 73 degrees F. The nominal size is 3/4 inch with a center-to-end dimension of 1.02 inches. This fitting carries FDA approval and NSF certification, making it suitable for applications where material purity standards must be documented and verified by a licensed installer or qualified trades professional.

This elbow is intended for high purity process piping, laboratory distribution, pharmaceutical, food and beverage, and other fluid handling systems where polypropylene is specified for chemical compatibility and cleanliness. Its 45-degree geometry allows directional changes in tight routing conditions without sharp transitions. Socket fusion installation is performed by qualified pipefitters or plumbers using appropriate fusion tooling sized for 3/4 inch polypropylene fittings.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch high purity polypropylene socket fusion piping systems where ASTM D4101 material compliance and NSF or FDA certification are required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter trained in thermoplastic socket fusion procedures. All system pressure must be relieved and flow isolated before cutting into an existing line. Fusion tooling must be clean, properly calibrated, and sized for 3/4 inch polypropylene to achieve a correct melt and joint integrity. Follow applicable plumbing codes and the fitting manufacturer fusion guidelines for heat time, joining force, and cooling hold time.
