Mission Rubber 801613 K Series Shielded Coupling Sch 40

Product Description

The MISSION RUBBER 801613 is a K Series shielded specialty coupling designed for joining pipe ends of differing nominal sizes in drain, waste, and vent piping systems. This coupling accommodates nominal sizes of 1-1/2 or 1-1/4 inches on one end and 1-1/4 or 1 inch on the other, making it a practical solution for transitioning between standard pipe sizes without additional fittings. It is compatible with copper, plastic, and steel pipe end styles and is rated for Schedule 40 and standard-wall pipe. Licensed plumbers and pipe fitters install this fitting during new construction, renovation, or repair work where dissimilar or stepped pipe connections are required.

This specialty coupling is suited for residential and light commercial plumbing applications, particularly in drain, waste, and vent configurations where transitions between copper, plastic, and steel pipe materials or sizes occur within the same run. The shielded design provides a secure mechanical connection that maintains alignment and resists separation. It is manufactured domestically and follows SCH 40 and standard-wall dimensional standards, ensuring a reliable fit with commonly available pipe stock.

Installation Notes

This coupling is installed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning work. Ensure pipe ends are cut cleanly, deburred, and free of debris before seating them into the coupling.
