TechLite® fitting insulation inserts are available in preformed or diaper form. The preformed inserts are precision ground to provide a good fit within the pipe tolerances. The diapers are conditioned at the factory to allow added flexibility to the TechLite®. Fabricated from high temperature melamine foam, the fittings have a service temperature of -150°F to +400°F. White or color coded low smoke 20 mil PVC fitting covers are shipped with the fitting insulation inserts. The PVC covers are UV inhibited and resistant to harsh weather conditions and many chemicals.
