Specifications
Widely used for connecting pipes and hoses that carry liquids, powders & granules. A ‘straight through’ connection is made allowing the free flow of substance being moved. It is only limited by the pressure of the application, and the chemical compatibility of the substance being moved with the coupler body and gasket.

Cam couplings have historically been made to the Mil Spec, MIL-C-27487, which has since been superseded by the Federal Standard A-A59326. This ensures compatibility between different product manufacturers also made to spec. The Mil Spec provides various specifications to be adhered to such as:  dimensions to be used; ratings for pressure; Materials to be used in manufacture; the methods of casting to be used; tolerances to be followed and the procedures for inspection. Our cam lock fittings are made to abide by the mil spec with regards to dimensions and various ratings. They are tested to ensure the confirm to the approved pressure ratings.

All our cam & groove fittings are manufactured with the ability to lock the handles in place using a safety pin. This ensures the adaptor and coupler remain connected.

Working Pressure Ratings (PSI)
Operating pressures are provided only as guidelines for ambient temperatures with elastomeric gaskets. A higher temperature will reduce the pressure rating of the cam lock coupling as will Teflon (PTFE) gaskets. Polypropylene camlock fittings only have a maximum working temperature of 158°F. At this temperature, the working pressures in the table below are to be reduced by an additional 40%. Recently the 4” couplers  been made with 4 handles to increase the operating pressure.

*All ½” couplers come standard with two handles.

Certification
General certificates of conformance available for stock parts. Since most parts are made to stock, full material trace certification (MTR) may be subject to special quotation and extended delivery.

Threads (ANSI B2.1-1968)
Proflow Couplings including the SNAPLOCK® Camlock line are designed to seal when threaded to a pipe. Manufactured in National pipe thread (NPT) in both Male NPT and Female NPT Threaded ends.

Non-threaded ends
Hose barb ends are found on the Type C and Type E. The hose barb is typically double ribbed, multi ribbed hose barbs can be manufactured on request as well as socket weld, butt weld or flange ends.

Aluminum Cam Locks
Gravity die cast, it is possible to anodized as is typical for military contracts.

Brass Cam Lock
Forged up to 3” and the larger sizes are sand cast.

Stainless Steel Camlock Fittings
Investment cast in SS 316. Can be mirror polished for sanitary and food grade applications.

Poly Camlock Fittings
Acid-resistant, manufactured from glass reinforced polypropylene.

Handles:
SS 304 handles for Stainless Steel and Polypropylene couplings. Brass handles for Brass and aluminum camlocks.

Pull Rings
Standard with all handles for easy opening.

Safety pins:
All female couplers come standard with safety pins that can lock the handles in place for extra security. Safty pins are not needed under normal working conditions.

 Gaskets:
All metallic kamlock fittings come standard with Buna Nitrile (Buna N) gaskets, While EPDM gaskets are standard for Polypropylene for added chemical resistance. Additional sizes and Material are available on request. We can supply PTFE (Teflon) gaskets, as well as  manufacture  up to 10” gaskets for special orders.

Cam and Groove Fittings Types and sizes

Camlock adapters are the male portion of the connection and fit into the female cam couplers which has arms. Both Male adaptors and female couplers come in Male NPT Thread, female NPT Thread and hose barb ends.

Camlock Fittings - General Dimensions

Cam locks are sized according tto the size of the hose or Pipe that they will connect to, and not to according to the ID or OD of the camlock itself. For Example a 3" Camlock will fit into a 3" hose or a 3" Pipe. All camlocks made to the Mil Spec will fit each other on the coupler/adaptor end, and the threaded end with screw into a NPT pipe of the same size. For example a 2" Cam and Groove will screw into a 2" Pipe.

Cam Lock Hose Fittings Common Applications

 Applicable to almost any industry that uses liquids, powders or granules. Used where ever pipe, tubes or hoses transfer product. Here are some examples of the industries where Cam lock quick disconnect couplings are used:

Food & Beverage
½” Stainless Camlocks are used in Home brew. Dairy farms and Wineries also readily use these fittings in larger sizes.

Maple Syrup
In recent years ½” cam lock quick connects have become commonly used for connecting silicon tubing and connecting evaporators in the production of maple syrup.

Diesel and Fuel
Cam lock pipe fittings are used on fuel tankers as a means to connect Fuel lines. All companies that dispense fuel on site will have a fuel pump and often connect the plumbing with quick release couplers. Companies like Tecalemit Inc. who install Fuel dispensers will readily use 2” and 1 ½”couplers for installation.   

Agriculture
Due to their acid resistant qualities, Poly Camlocks are widely used as hose connectors on agriculture sprayers and similar applications.

Oil Distribution
Camlock Hose connectors are used for fuel delivery to service stations and private premises.

Connecting Pumps
Cam lock hose couplings are widely used threaded into pump inlet/outlets. This allows the quick release and quick connection of transfer hose.

Water
Water purification plants and water conditioning plants Like Siemen’s water and RK Water conditioning readily use large pipes and will require kamlock couplings to connect. They are also used for water cooling processes.

Paints
Companies like PPG paints routinely use Stainless couplers due to their suitability for paints, inks & dyes.

Fuel Polishing
When fuel is circulated and pushed through filters for cleaning, camlock hose couplings allow for easy hose connections.

Cleaning
Every industry requires some sort of cleaning and for this water hoses are often required. Cam lock hose connectors allows disconnection of hose for storage purposes.

Military and Government bids                                                                                                            
Made to the new specification A-A-59326, which replaced the US military specification MIL-C-27487, these couplings are used by the US military nationwide. Anodized Aluminum couplings made to the Mill spec can be special ordered.

Camlock Quick disconnect Special orders

Since we have such a good relationship with our manufacturers we are able to place orders of extra large sizes and have quick delivery. Even orders of thousands of pieces per order are routine and easy to do. As well as oversized orders we can also do small specialized orders, often with no minumum order quantiites. We can manufacture Reducer couplings with reduced theads as well as spool adaptors and female coupler by coupler.  We also have the ability to modify existing Camlocks for special OEM applications. Feel Free to call us or send and email and we will be happy to quote any special parts. If this is routine bussines we will also consider stocking these parts and shipping as needed.
