How to measure Camlock fittings

Buying the incorrect part or component can cost a business valuable time and money. So, make sure you make the right choice when you purchase your Camlock fittings by knowing the correct size you need for your project. We’re going to explore how to measure a Camlock fitting, and some additional factors to consider when making your purchase.

What is a Camlock fitting?

Also known as cam and groove couplings, Camlock fittings are useful tools for those working in industrial and construction areas. They allow you to connect, or disconnect, joints in a pipeline or hose, giving the user control and ensuring the piping functions properly. However, finding the correct size for your Camlock fitting is sometimes tricky. The wrong part could cause more significant structural damage, or pose a safety risk, thereby increasing your cost in the long run. So, you must take the appropriate measurements and order correctly the first time around.

Measuring a Camlock fitting

To measure a Camlock fitting, you need to match up the diameter of the pipe or hose with the cam coupling. Depending on the part, it’s best to measure both the inside diameter (ID) and the outside diameter (OD). As coupler fittings have two ends, the female which is the coupler (ID) and the male which is the adapter head (OD), it’s essential to know how these fit into the rest of your system. Both the OD and the ID should match, and if the Camlock is non-threaded, it should match the pipe size too. For Camlocks with threaded female or male parts, they’ll need to be slightly larger than the pipe’s diameter. We’d recommend that you use an electronic ruler, otherwise known as a digital caliper. These can help you gain accurate measurements and are perfect for smaller objects thanks to their jaws. In the case of Camlock fittings, the inside and outside jaws allow you to measure both diameters with minimal room for error.

Factors to consider

Beyond the numeric measurement of your Camlock’s diameter, there are other things to consider when finding the best fit for your piping. Some of these factors include the material, thread type, and application.

Material

There are a variety of materials used to make groove coupling, and these have different uses and benefits across a range of industries. The part’s material can also affect the choice of size. For example, in a metallic Camlock fitting, a 1-inch Camlock coupling matches the 1-inch measurement of the Camlock’s diameter. For materials like polypropylene, there are variations from country to country due to the absence of any international standard size. If you’re in any doubt, then contact your supplier or the manufacturer for advice. Some choices, when considering the material, include:

• Aluminium- These Camlocks are lightweight and resistant to corrosion. While robust, they are not the most reliable option.
• Stainless steel- Often, the first choice for pharmaceutical and food processing due to their hygiene, they are highly resistant to corrosion and extremely durable. While more expensive, steel is often the most cost-effective solution for the long-term.
• Polypropylene- As the cheapest options, these Camlock’s are best for areas of high moisture like in agriculture or chemical processing.

Thread type

In taking your measurements, it’s essential to know whether you need to take an ID or OD reading. Some of the standard types of Camlock fittings include:

• Type A - Male Camlock with a female pipe fitting
• Type B - Female Camlock with a male pipe fitting
• Type C - Female Camlock with a male hose barb
• Type D - Female Camlock with a female pipe fitting
• Type E - Male Camlock with a male hose barb
• Type F - Male Camlock with a male pipe fitting

Application

Knowing which industry your coupling is headed for can help you choose the part you need. Understanding what materials your piping will transport, and the volume of this material is essential in selecting the type of Camlock. The size and diameter measurements of a Camlock are particularly essential here, as putting too much pressure on the part can cause it to break or be rendered ineffective. Overall, when measuring for a Cam fitting, it’s essential you take accurate diameter readings of both the ID and OD. It’s also important to consider how the Camlock will fit into the broader system of your operations, so you can appropriately choose the size and material of your Camlock.
