Flexible closed cell elastomeric pipe insulation
Designed for the professional contractor

K-FLEX® LS SEAM-SEAL Pipe Insulation is an environmentally friendly, CFC-free, flexible elastomeric insulation, pre-slit with a factory applied pressure sensitive adhesive. It is black in color and identified as K-FLEX® LS. This superior closed cell insulation is designed to retard heat flow and prevent condensation when properly installed. K-FLEX
® LS SEAM-SEAL Pipe Insulation is pre-slit with a factory applied specially formulated long-lasting bonding adhesive applied to both seam surfaces and comes with convenient built-in release liners which allow for easy installation. It is available in wall thicknesses of 3/8" through 1" and in sizes ranging from 3/8" to 4" IPS. K-FLEX® LS SEAM-SEAL key physical properties are approved through supervision by Factory Mutual Research Corporation. It is non-porous, non-fiberous and resistant to mold growth.

K-Flex USA elastomeric insulation products are GREENGUARD® certified as low VOC materials, meeting the requirements of the“Children and Schools” classification, the most stringent requirements. Additionally, all K-Flex USA elastomeric insulation products are GREENGUARD® listed for mold resistance and meet the “mold resistant” criteria.

K-FLEX® LS SEAM-SEAL has the same excellent insulation properties as standard K-FLEX® LS and is used on similar applications such as refrigerant lines, cold water plumbing, roof drains and chilled water systems. K-FLEX® LS SEAM-SEAL is recommended for applications ranging from -70˚F to 200˚F (-57˚C to 93˚C) for both new and existing applications.
For best results, store and install K-FLEX® LS SEAM-SEAL at temperatures above 40˚F (4˚C).

K-FLEX® LS SEAM-SEAL’s closure system is designed to save labor costs, particularly on straight runs. It greatly reduces the use of contact adhesives, thus allowing for improved working conditions and compliance with OSHA requirements. K-FLEX® LS SEAM-SEAL has superior cold weather flexibility. K-FLEX® LS SEAM-SEAL can be used with heat tracing/heat tapes.

K-FLEX® LS SEAM-SEAL offers the advantage of easier handling handling& installation.
  • Faster install
  • Ideal for straight runs
  • Less use of contact adhesives
