Camlock coupling

Tool-free rapid connection for discharge, loading and transfer lines carrying fluids and bulk materials.

Product Overview

A Camlock (cam-and-groove) coupling is a quick connection for transferring fluids and bulk materials at low to medium pressure, opened and closed with locking cam arms and without special tools. It is commonly used on fluid discharge and loading lines, mobile tanks and industrial ancillary equipment. Tose'e Tejarat Sayyalat supplies this product alongside its hydraulic couplings.

Applications

  • Discharge and loading lines for fluids and bulk materials
  • Connecting hose to mobile tanks and tankers
  • Industrial ancillary equipment requiring rapid connection and disconnection

General specification

Operating typeRapid connection and disconnection with locking cam arms, without tools
Common size rangeFrom 3/4 inch to 6 inch
Common typesMale and female (Types A to F, plus DC/DP) according to the line's duty
Pressure applicationSuitable for transferring fluids and bulk materials at low to medium pressure
Please note: The exact Camlock type and size are determined by the line's duty (suction or discharge) and by compatibility with the coupling on the other side.

TypeConnection arrangementApplication
Type AMale adapter × female threadConnects to male-threaded parts such as nipples and hose tails
Type BFemale coupler × male threadConnects to female-threaded parts such as pipe fittings
Type CFemale coupler × hose shankConnects directly to the hose end on the coupler side
Type DFemale coupler × male NPT threadHose connection with a male NPT thread
Type EMale adapter × hose shankConnects directly to the hose end on the adapter side
Type FMale adapter × male threadConnects to valves, pumps and female-threaded fittings
Type DCCoupler dust capProtects the female coupler when not in use
Type DPAdapter dust plugProtects the male adapter when not in use
Source: The table above follows the common industry standard for Camlock (cam-and-groove) couplings, MIL-C-27487 / A-A-59326 — the same standard to which Alfagomma and OPW couplings are made, and with which they are dimensionally interchangeable.

In plain terms: The letter against each Camlock type (A to F) indicates which side of the joint is male and which is female, and what it connects to — hose or pipe. Choosing the wrong type is the most common cause of mismatched Camlock orders, so always state the exact type (A, B, C, D, E, F, DC or DP) in your enquiry.
