Description
Overview
This gravity drop coupler joins a road tanker outlet to a tank inlet so fuel can be offloaded by gravity. It is a 4 inch coupler with a 3 inch BSP thread, in aluminium, and it is the female half of the connection. Pick it by the thread size on your tank or hose adaptor: this one is for 3 inch BSP, and the near-identical 4 inch BSP version is listed separately. Matching the thread first saves a return trip when the driver arrives on site and the fitting does not screw home.

Where it works
Tanker operators and depots use gravity drop couplers wherever fuel is offloaded straight into a storage tank: fuel depots in Gauteng and KZN, mine fuel bays in Mpumalanga coal country, and farm bulk tanks in the Free State and Limpopo. It suits tanker fleets that service remote sites where there is no pump on the receiving end. For the 4 inch thread version, see the 4 inch x 4 inch BSP coupler, and for the other half of the connection, the 4 inch male gravity drop coupler. More fittings sit in our fuel station accessories category.

Questions about this product
What is a gravity drop coupler used for?

Is this the male or female coupler?
This is the female gravity drop coupler. The matching male half is a separate product, listed as a 4 inch male gravity drop coupler, and there is a male version with a sight glass as well. If you are replacing a pair, order both halves so the fit is correct.
