API Couplers

Since the mid 1970’s the petroleum distribution industry has been switching its tanker filling methods to bottom filling operations. The key factor that has united virtually every loading point worldwide are API couplers and of the specification API RP1004.

This dictates the profile of the nose piece on the tanker filling adapter. That profile means that each and every manufacturer of loading arm couplers has to be able to connect to and disengage cleanly from, the adapter with that profile.
