Nomaco DGS13810 Self-seal Pipe Insulation 1-3/8 in Id

Product Description

The NOMACO DGS13810 is a self-sealing closed-cell foam pipe insulation sleeve designed to reduce heat gain and prevent condensation on cold water, chilled water, and refrigerant piping. With a 1-3/8 inch inner diameter and a 1 inch wall thickness, it delivers substantial thermal resistance in a pre-slit, self-adhesive format that speeds field installation. The 6 foot length suits standard residential and light commercial runs. Plumbers, HVAC technicians, and mechanical insulation contractors are the primary installers of this product type.

This insulation is suited for cold-service and dual-temperature piping applications, including chilled water lines, domestic cold water supply, and refrigerant suction lines where condensation control and thermal efficiency are priorities. The self-seal lap joint eliminates the need for separate adhesive on the longitudinal seam, making it practical for both new construction rough-in and retrofit insulation work in tight spaces.

Key Features

• Self-sealing lap seam — no separate contact adhesive required for the lengthwise joint
• 1 inch wall thickness provides substantial thermal resistance for cold-service and dual-temperature lines
• 1-3/8 inch ID fits standard pipe sizes used in chilled water and refrigerant suction applications
• 6 foot section length reduces the number of end joints per run
• Closed-cell foam construction resists moisture vapor transmission and inhibits condensation

Compatibility

The DGS13810 is a recognized cross-reference for several manufacturer part numbers including ARMACEL/ARMAFLEX DGS13810, IMCOA/NOMACO 138ET, 6IL100138, and 6L100138, Jones Stephens I57-138, K-FLEX 7PXL100138, LSP F-13810-SS, and Sioux Chief 663-13810SS.

Installation Notes

Mechanical insulation of this type is typically installed by plumbers or HVAC technicians in accordance with local mechanical codes and ASHRAE 90.1 insulation thickness requirements. Pipe surfaces should be clean, dry, and free of oils before the insulation is applied to ensure the self-seal adhesive bonds properly. On end joints and butt seams, use a compatible foam insulation adhesive or self-sealing tape rated for the application temperature. Do not stretch the sleeve during installation, as distortion reduces effective wall thickness and thermal performance.
