When it comes to Long Radius fittings PIC has you covered with over 115 different sizes. Each is made for a specific pipe/insulation combination; no more trying to use one cover for multiple sizes.
All white fittings start out with hing gloss E-84 approved low smoke and UV stabilized sheets before being formed to exacting standards. Fittings are then sealed with PIC welding adhesive for a neat appear and easy installation (Note: Fittings 20.0 and larger in OD are unsealed for shipping purposes). Remember, there is no additional charge for color.
