Specify with confidence
The details that shape your selection.
Start with connection type and service access, then define mating parts, fluid conditions and quantity.
- Function and loop position
- Interfaces, drawing revisions and envelope
- Coolant, materials and seals
- Temperature, pressure and flow conditions
- Testing and documentation
- Quantities and delivery requirements
System and selection context
Connection selection starts with the two components being joined, the service sequence and access to the joint. Quick disconnects and fittings solve different tasks and need different interface checks.
Inputs for review
Identify plug and socket or both fixed ends, the exact thread or mating revision, coolant, pressure and leakage conditions. Compare a requested alternate only after the interface and acceptance method are controlled.
Information to prepare
- Start with connection type and service access, then define mating parts, fluid conditions and quantity.
Configuration and quotation
Include the drawing or specification revision and identify any requirements that are still to be confirmed. Available configurations, testing and documentation are confirmed with quotation.
