Nomaco Kflex Drain Trap 4-1/2 in ID

The Nomaco Kflex 6RX068448 is a drain trap designed for plumbing installations. It features a nominal inside diameter of 4-1/2 inches and a total length of 6 feet. The body is constructed from NBR/PVC based elastomeric material in black. This component suits pipe sizes of 4 inches with a 3/4 inch wall thickness.

Suits 4 in pipe systems needing thermal protection

Installers working with 4 inch pipe requiring insulation across a broad temperature range will find this trap suitable. The material handles continuous exposure from -297 degrees F up to 220 degrees F. Buyers needing a different nominal inside diameter or a slit insulation style should look at alternative drain components. Those requiring a higher or lower R-value must select a different specification.

Deciding spec is the 4-1/2 in nominal ID

The single specification that determines fit is the insulation nominal inside diameter of 4-1/2 inches. This must match the outer diameter of the pipe being insulated to ensure proper coverage. The trap carries an approximate R-value of 4.4 for thermal resistance. Verify the pipe size compatibility before purchase as the product contains a chemical regulated under California Proposition 65.
