Elastomeric Tee for 4-1/8" Tube

The Nomaco Kflex 801-T-100418 is a pre-formed black tee fitting made from NBR/PVC based elastomeric insulation. It is designed to maintain thermal protection at a branch connection on 4 inch iron pipe size tubing. The fitting covers the joint in a single piece without the need for cutting and mitering straight lengths.

Suited for closed-cell pipe insulation systems

This tee suits installers working with 1 inch wall thickness insulation on 4-1/8 inch outer diameter tubes carrying fluids between -297 and 220 degrees F. It is not intended for pipe sizes outside the 3-1/2 inch nominal bore or for applications requiring a different insulation thickness or material composition.

Wall thickness of 1 inch

The insulation wall is 1 inch thick and carries an approximate R-value of 5.9. This single figure determines whether the fitting matches the thermal resistance specified for the rest of the pipe run.

Questions about this item

How often does the NBR/PVC elastomeric material on this tee trap need replacement under normal conditions?

The NBR/PVC elastomeric body is rated for continuous service from -297 °F to 220 °F and does not have a scheduled replacement interval; inspect periodically for physical damage or compression set.

What temperature limit is reached first during sustained high-temperature operation?

The upper service limit is 220 °F; sustained exposure above this temperature will degrade the NBR/PVC insulation before any other limit is encountered.

How much heat does the fitting radiate when the system runs all day at design temperature?

With an approximate R-value of 5.9, the 1-inch thick NBR/PVC wall limits surface heat loss to a low level during continuous operation at up to 220 °F.
