For Adaptall products, the thread types for each description are displayed hose/tube and/or male side first, then port and/or female side (please refer to the Conversion Adapter Identification Guide for details). If both sides of a fitting are the same (both hose/tube or both port) they are displayed alphabetically. For example, a BSPP x NPT nipple has two port threads; according to alphabetization, this description would read BSPP male x NPT male. Part descriptions are then arranged in alphabetical order, with males appearing before females. For example, a male BSPP is typically the first listed while a female SAE O-ring Boss is last. Thread types are displayed first to allow for quick searching along the margin (as opposed to thread gender first which is common). Test port tees are not conversion adapters, rather they are meant to be placed in line with your current hydraulic system allowing for the implementation of a pressure gauge, for example. They consist of a male and female (swivel) that are always identical thread types. Test port thread types and sizes vary from fitting to fitting but are always female.
