Description
Overview
This gravity drop coupler has a 4 inch coupler end and a 4 inch BSP thread, and it lets a road tanker discharge into a storage tank under gravity. It is the larger-thread version of the 4 inch x 3 inch model, so the one thing to check before you order is the thread on your tank inlet or adaptor. The body is aluminium, and at 1.6 kg it can be fitted and removed by one person at the tank without lifting gear. A coupler that matches first time keeps the tanker moving and keeps the driver off the phone.
Key features

- Aluminium body, light and corrosion resistant

- Net weight 1.6 kg, compact at 220 x 220 x 180 mm
- Taller body than the 3 inch BSP version, which is 140 mm high
Where it works
You will find these fittings at fuel depots in Gauteng and KZN, on farm bulk tanks across Limpopo and the Free State, and at mine fuel bays in Mpumalanga. Wherever a tanker drops product by gravity into a fixed tank, the coupler is the part that gets used on every delivery and wears first. If your inlet is 3 inch BSP instead, choose the 4 inch x 3 inch BSP coupler. For the mating half, see the 4 inch male gravity drop coupler. Everything else for the offloading point is in our fuel station accessories range.

Questions about this product
How do I know if I need the 3 inch or 4 inch BSP thread?
Check the thread on your tank inlet or adaptor. If it is a 4 inch BSP thread, this coupler is the one; if it is 3 inch BSP, choose the 4 inch x 3 inch model instead. Both have a 4 inch coupler end. Send us a photo on WhatsApp if you are unsure and we will confirm.
Can I use it to pump fuel under pressure?
It is designed for gravity offloading of road tankers, not for pressurised transfer. For pumped transfer use dry break or camlock couplings rated for the job. We do not state a pressure rating for this coupler, so ask us if your application involves anything other than gravity flow.
Do you deliver to Rustenburg and Mpumalanga mines?
Yes. We deliver with our own trucks from Polokwane to all nine provinces in 1 to 3 days, including the North West and Mpumalanga. At 1.7 kg this coupler is in the first band: R550 for total orders up to 30 kg, and free from R20,000 VAT incl.
