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.
