Description

Overview

This gravity drop male coupler has a sight glass built into the body, so you can see fuel moving through the connection while a road tanker offloads. It is a 4 inch x 3 inch coupler in aluminium. The glass lets the driver confirm that product is flowing, and spot air in the line or a blocked outlet without disconnecting anything. That small window saves time on every delivery and helps catch problems before a tank runs short. At 2.6 kg net it is heavier than the plain male coupler because of the glass section.

Key features

  • Integrated sight glass for visual flow checks
  • 4 inch x 3 inch male gravity drop coupler
  • Aluminium construction, body 220 x 220 x 180 mm
  • Net weight 2.6 kg
  • For gravity offloading, with the female half fitted at the tank

Where it works

Tanker fleets and depots choose the sight glass version where the driver needs to see what is happening at the connection: remote farm tanks in Limpopo and the Free State, mine fuel bays in Mpumalanga, and municipal depots in Gauteng and KZN. If you only need a plain connection, the 4 inch x 4 inch male coupler is lighter and cheaper. To add a separate inline window to a line, see the 4 inch sight glass. The wider selection is in our fuel station accessories category.

Questions about this product

What is the sight glass on a gravity drop coupler for?

It lets you see fuel moving through the coupler while the tanker offloads. You can confirm that product is flowing and notice air or a stoppage without breaking the connection. It is a visual check only, so keep your normal dipping and delivery-note checks in place when the tank is filled.

Is the 4 inch x 3 inch size right for my tank?

The 4 inch x 3 inch size refers to the coupler and its second connection. Match it to your existing female coupler and thread before ordering. If you are unsure, send us a photo of the fittings on WhatsApp and we will confirm the correct model, including the 4 inch x 4 inch alternative.

What does delivery cost to the Karoo or Northern Cape?

At 2.7 kg this coupler sits in the first band: R550 for total orders up to 30 kg, whichever province it goes to. Orders from R20,000 VAT incl. are free. Our own trucks deliver from Polokwane in 1 to 3 days, and we will confirm timing to remote farms.
