1/2" Iron Pipe Size x 3/4" Copper Tube Size x 72" x 1/2" Wall Rubber Insulation Cover

K-Flex 6RX048068 – 3/4" ID x 1/2" Wall Elastomeric Pipe Insulation, 6' Length

The K-Flex 6RX048068 is a flexible, closed-cell elastomeric pipe insulation engineered for mechanical systems requiring effective thermal protection and condensation resistance. With a nominal inner diameter of 3/4" and a 1/2" wall thickness, this 6-foot insulation length is suitable for 3/4" copper tube size (CTS) or 1/2" iron pipe size (IPS) applications.

Manufactured in the USA, this insulation product is used in HVAC, refrigeration, and plumbing systems to minimize energy loss, maintain thermal consistency, and prevent moisture accumulation on cold or chilled water lines. It is designed to meet industry performance and code requirements for commercial and residential environments.

Installation Notes

For optimal results, ensure the pipe surface is clean and dry before installation. The insulation can be trimmed with a utility knife for custom lengths. All seams and terminations should be sealed using a suitable contact adhesive or tape to maintain the vapor barrier and thermal integrity. Follow all applicable building codes and manufacturer guidelines during installation.
