Vapour Adaptor - VCM3P


The VCM3P is a poppet sealed cam and groove connection for truck vapour return lines that comes with a proximity switch holder.

The VCM3P series has an aluminium body with a 100mm (4") TTMA flange for mounting. The seals are Viton and the shaft runs in a delrin bush.

A standard camlock will not fit into this adaptor, only an approved vapour coupler will fit.

Features & Benefits
  • Automatic opening when vapour coupler is connected and automatic closing when coupler is disconnected.
  • All aluminium construction with stainless steel springs and viton poppet seal.
  • High flow rates and low pressure drop.

When female coupler is connected, the poppet is pushed inwards to allow vapour flow. The outer diameter of the female coupler pushes the striker plate forward and is detected by the proximity switch to provide electrical signal that vapour recovery is connected.

Poppet Opening Pressure
Poppet opens under external pressure of 4-6 kPa for vacuum relief.

Pressure Drop
Pressure drop less than 4 kPa at 6,000 litres/min flow of free air across coupled connection.

4” (100mm) TTMA flange (8 x Ø11 holes on 149mm PCD).

Nosecone is standard 4” NATO camlock with interference selectivity ring to prevent wrong connection.
