The assembly of a Camlock coupling consists of two pieces: a male plug and a female coupler. Figure on side shows the components and process for connecting and disconnecting Camlock couplings.

1. The coupling handle should be extended outward, and the correct male plug should be placed into the female coupler (Figure labeled A).
2. The two halves should be firmly locked together by closing both handles simultaneously (Figure labeled B). Closing both handles simultaneously ensures that the grooved plug is consistently pushed down onto the seal, guaranteeing a leak-proof assembly for the safe transfer of liquids.
3. Ensure that the camlock hose assembly is de-pressurized before reversing the process to disconnect the fitting (Figure labeled C).

There are several types of camlock fitting, all described below

Camlock couplings are identified by their type designations, which are listed below while the image shows a visual reference for the various coupling types.

1. Type A: Plug with female thread
2. Type B: Coupler with male thread
3. Type B-AS: Coupler with weld end
4. Type C: Coupler with hose tail
5. Type D: Coupler with female thread
6. Type E: Plug with hose tail
7. Type F: Plug with male thread
8. Type F-AS: Plugs with weld connection
9. Type DC: Dust cap for plugs
10. Type DP: Dust plug for couplers
11. Type DA: Female coupler with male camlock adapter

Before purchasing, various factors should be considered to get the correct fitting for the application. Below is a list of the primary selection criteria for Camlock couplings.

Camlock couplings and plugs have slightly different sizes, female couplers are therefore measured on the inside (A), while male plugs are measured on the outside (B). For more details see the figure on the side

Camlock coupling sizes are determined by their nominal size, where the male and female couplings have slightly different sizes for coupling purposes. The male plug (Figure above labeled B) is measured on the outside, while the female coupler is measured on the inside (Figure above labeled A).

The temperature specifications of the coupling are determined by the material chosen. For example, 70 °C (158 °F) is the maximum temperature that polypropylene can handle, at which pressures must be reduced by 40%. When stainless steel is used, the operating temperature ranges from -150 °F to 500 °F (-101 °C to 260 °C). Due to these differences, it pays to know the application's exact details and working temperatures. Remember that the minimum and maximum operating temperature depends on various factors besides the material the Camlock coupling is made of. These include, but are not limited to the operating pressure, media used, outside factors like weather, etc.

The table below shows the advantages and disadvantages of each material and how they can be used for various applications.

Camlock fittings are specially coated to protect them from highly aggressive chemical agents. This is because some standard materials, like stainless steel, cannot withstand those situations. For example:

1. >ECTFE (ethylene chlorotrifluoroethylene): Couplers coated in ECTFE demonstrate excellent electrical insulation, fire, and corrosion resistance, and can withstand temperatures up to 150 °C. These couplings have been designed to resist highly concentrated and aggressive chemicals.
2. >PFA (Perfluoroalkoxy alkanes): PFAs are particularly well suited for food and pharmaceutical industries because of their high-temperature resistance.
3. >PTFE (Polytetrafluoroethylene/ Teflon): These coatings can withstand temperatures up to 260 °C and are as effective as PFA coated couplings for food-grade applications.
4. >PVDF (Polyvinylidene difluoride): The coatings are wear-resistant and are also suitable for food industry applications. They are resistant to highly concentrated and aggressive chemicals and have the advantage of high temperature resistance up to 260 °C.

For the maximum operating pressure ratings for Camlock couplings, see the below table. The pressure rating is the pressure at ambient temperature.

All metal Camlock couplings and polypropylene Camlock fittings are supplied & fitted with either a NBR, EPDM, or a PTFE (teflon) seal. Different sealing compounds are available depending on the media being conveyed through the couplings. There are replacement seals available made of the following materials:

• FKM (FPM)
• CSM (Hypalon)
• Teflon PTFE/NBR compound
• Teflon PTFE/FPM compound

For applications requiring more exotic sealing solutions, chemical encapsulated seals are available made of silicone or FEP.

This is a quick connector type, and as for all quick connectors, must be inspected periodically (mandatory). Below our recommendations

1. Always follow the design pressure which the fitting was built
2. Use fluids according to the characteristics of the fitting material
3. Never modify the connection according to your experience. The fitting has been already build and tested based on ENGs
4. Under pressure the fittings must be locked through the "Camlock Coupling Chain"
5. Depressurize Before Disconnecting: Always ensure that the system is fully depressurized before attempting to disconnect the fittings to prevent accidents.
6. Never mix the material between fittings
7. Correct Usage: Use camlock fittings within their designed pressure and temperature ranges. Exceeding these limits can lead to fitting failure and safety hazards.
8. Never mix the materials between fitting as shows in figure below
