Everything You Need to Know About Cam Locks

• MEI Locks is paramount quality cam-locks
  supplier, complies with the highest quality
  standards. These locks are perfect for
  accommodating.

• Picking readymade locks for fittings can be
  tricky. A good lock must accommodate perfectly,
  without any visible fittings. This article
  provides a comprehensive overview of cam-lock
  fittings available, accessories, selecting the
  right fitting, maintenance, etc.

How to choose a readymade lock?

• There are few considerations while picking the
  perfect lock for your doors. First, the type of
  door has to be identified. Whether it is sliding,
  folding, flush fitting, or wooden, etc. Next,
  finishes, texture and touch are to be assessed.
  This includes looking for carvings, moldings, and
  the thickness of stiles and rails. Third, price
  has to be considered. Since, quality determines
  the price, hence you can figure out what quality
  product you want to get. The fourth and yet
  another important thing to consider is
  aesthetics.

What is a Cam-lock fitting?

• Known as groove coupling, a cam-lock fitting
  connects two hoses together in different
  materials so that material from one can be
  transferred to the other. Because of their ease
  to use, cost-effectiveness and efficiency, they
  are highly popular for coupling.
• Cam-lock fittings have a wide usage because of
  their versatility. They are easy to maintain and
  dont get damaged easily because they dont
  require threads for connecting the coupling
  halves. They are ideal for using in industries
  such as petroleum, and chemical trucks.

How Does a Cam-lock Work?

• A Cam-lock consists of two parts- an adapter and
  a coupler.
• To connect, slide outwards the clamps on the
  coupler, and fix the adapter into coupler while
  considering their sizes. Once both halves are
  firmly fixed, close both clamps at the same time.
  Closing both clamps at the same time ensures that
  the seal is tightly assembled for safe transfer
  of liquids because the adapter is pulled down
  consistently.
• To disconnect, depressurize the hose assembly
  first and then reverse the process.

How to Measure the Dimensions of Cam-lock?

• For a flawless cam-lock fitting, it is important
  to take precise measurements. Measuring a
  metallic cam-lock fitting is simple. The hose
  tails measurements define the cam-lock size.
  Whatever the size of hose tail is, that would
  become measurement of cam-lock coupling.
• Polypropylenes measurement is bit different,
  because the head sizes of each manufacturer vary
  and they do not have any international standard.
  There are variations in measured size and the
  fitted body. Generally, cam couplings are
  measured by measuring the Outside Diameter of the
  head, or the Inside Diameter of the coupler.

How to Choose the Right Cam-lock Fitting?

• The fitting specifications include seven fields,
  known as STAMPED. In Stamped, S is for Size, T
  for Temperature, A for Application, M for
  Material/media, P for Pressure rating, E for End
  fittings and thread type, and D for Delivery.
  Delivery means additional information such as
  material certs.

What is the Standard for Cam-locks manufacturing?

• The standard for groove couplings is Mil-C-27487,
  US military specification, now replaced with
  A-A-59326D. Both standards are compatible, which
  allows interchangeability of couplings using the
  same specification. The Mil-C-27487 standard was
  based on materials, tolerances, inspection
  procedures, casting methods, dimensions, and
  pressure ratings. Best lock manufacturer comply
  with defined standards.

9
European Standard

• Approved by The European standard, EN 14420-7 is
  applied to cam groove couplings. It is
  manufactured as per American military standard
  discussed above. The hose connection does not
  follow this standard it is only applicable to
  the coupling.

10
Can Cam-locks be interchanged?

• The cam groove couplings can be interchanged
  between different manufacturers. However, these
  sizes cannot be accommodated- ½ (12.5mm), 5 and
  8. Because of different versions of cam Groove
  in the market, A-A-59326A Mil Specification does
  not apply to 5 and 8.

11
What Are the Limitations of Using Cam-locks in
Assemblies?

• At times, the hose shanks with rough edges are
  hard to connect with ferrule or sleeve. An effort
  to fit them together can permanently damage the
  hose, by cutting into the inner wall of the hose.
  This can cause leakage or hose failure. Also, Cam
  Groove couplings cannot be used for steam or
  compressed air applications.

Why you Need High Quality Cam-locks

• Although, there are many manufacturers of
  cam-locks out there, but not all of them
  Specialty lock manufacturers. This becomes even
  more complicated if both halves of the coupler
  are from different manufacturers. This problem
  does not arise for North American or European
  manufacturers because they follow accepted
  certified specification rigidly.
