Family context
Sealfast Dry Disconnect couplings have an automatic shut-off valve in BOTH halves — when disconnected, both the coupler and adapter close their valves, eliminating product spillage. Used for fuel, solvent, acid, and aggressive-chemical transfer where any drip is unacceptable (chemical loading, refuelling, hazardous-fluid handling). Available with Viton (FKM) seals for petroleum / fuel / oil service, or PTFE seals for the most aggressive chemical service. Cam-and-groove style engagement on the connection face.
How to order
Specify (a) the size, (b) the body material from the available options, and (c) any special seal / gasket requirements. Indus engineering will confirm the exact Sealfast part number on the RFQ. For Bauer couplings, specify the Bauer-standard size code (2", 3", 4", 5", 6", 8") and end configuration. For Dry Disconnect, specify the seal compound (Viton FKM for petroleum / fuel; PTFE for aggressive chemical) — selection drives the part number.
Companion products
Pair with matching cam-and-groove halves (specialty cam-and-groove), Bauer-standard mating couplings (Bauer Type), or matching dry-disconnect adapter/coupler (Dry Disconnect). Browse the Sealfast Couplings range for the full product family.
