Trakya Döküm Taper Seat Union
Trakya Döküm Taper-Seat Union
Trakya Döküm taper-seat unions are three-piece fittings that join pipelines and allow the line to be easily disconnected and reconnected when needed, without rotating the pipes. Thanks to the conical seating surface (metal-to-metal contact), they provide superior sealing performance under high pressure.
