Parker 475298 Elastic Sealant Off-white 100 Foot

Product Description

The PARKER 475298 is an elastic sealant formulated for sealing joints, seams, and openings in mechanical and building systems. It applies as a flexible, off-white compound that accommodates movement and thermal expansion in the joint without cracking or losing adhesion over time. With a coverage length of 100 feet, a single package is suited for larger runs on ductwork, pipe penetrations, or structural seams. Licensed HVAC technicians, plumbers, and sheet metal contractors are the primary installers of this type of sealant in both new construction and service applications. The product ships as a single unit with a minimum order quantity of one package.

This elastic sealant is appropriate for residential and light commercial applications where flexible sealing is required at joints, seams, and openings. Common installation scenarios include duct seams, pipe-sleeve penetrations through walls or floors, and any assembly point subject to vibration or cyclical movement. Its off-white color blends with common mechanical system surfaces and does not require color-matching in most concealed installations. The 100-foot length makes it practical for production installs or multi-point service calls where several joints require attention in a single visit.

Installation Notes

Surface preparation is critical before applying any elastic sealant — clean the substrate free of dust, oil, and loose material to ensure proper adhesion. Power down or isolate the system section being serviced before applying sealant to live ductwork or piping. Allow full cure time per the application environment before returning the assembly to service. Installation in HVAC duct applications may be subject to local mechanical codes or SMACNA guidelines; verify requirements before use.
