A combination of PITA™ and OPRA™ technologies designed specifically for FRP piping and equipment flanges

The FR-PITA®'s hybrid design provides chemically compatible, secure seals in applications with brittle, under-bolted flanges involving FRP or plastic piping. It utilizes the reduced area of the OPRA™ design and concentrated bolt load on the corrugated insert, creating optimum sealing with minimum seating stress. The ePTFE facing of the FR-PITA™ provides broadest chemical compatibility and easily conforms to warped or uneven flanges yielding a tighter seal.
