Properly measuring a sanitary fitting and knowing what size to order can be a common problem. This is our top reason for returns, regardless of the type of fitting or gasket being ordered. Here are some tips on how to measure a sanitary fitting.
Regardless of the fitting type being measured, the OD of the tube will be the fitting or gasket size you will need. If you look at the diagram below, most people will measure the Outside Diameter/OD (item A in the diagram) and assume that is the size of the fitting, but this is incorrect. Others will measure the Inside Diameter/ID (item I in the diagram), but this is incorrect also. The proper way to measure for a fitting size would be to measure the OD of the tube (item O in diagram). For example, a 2-inch Tri-Clamp Ferrule will have an OD (item A in diagram) measurement of 2.5", ID (item I in diagram) of 1.87", and a Tube (item O in diagram) size of 2".

As we progress into the new year, have you set any goals? Perhaps you would like to increase safety measures in your plant. Maybe you want to implement a color-coding system. Or possibly, your 2020 objective is to enhance organization. Organizing, identifying, and labeling your storage and inventory areas will help your plant to operate more efficiently.
Regardless of the goal, Nelson-Jameson is here to help you succeed in the new year. We offer a wealth

During our conversations with regulatory folks, a common theme has developed. Overwhelmingly, regulators have stressed the importance of a “culture of food safety”. This means that food safety isn’t relegated to only a few individuals in a plant. Instead, a culture of food safety is one where a business has inclusively brought in ALL stakeholders, from CEOs to part-time employees to learn, practice, and respect food safety standards. Instead of viewing food safety as only rules that haveto be followed or marks to simply check off on a sheet, food safety becomes a mindset and unifying goal across the plant and across the company.

What's a MERV...?
Minimum Efficiency Reporting Value (MERV) is the established air filter industry rating that measures the effectiveness of air filters based on the ASHRAE rating. The higher the MERV rating, the finer the filtration, meaning fewer dust particles and other airborne contaminants that can pass through the filter.
For example, a MERV-13 filter has to catch 90% of particles in the 1-10 µm ranges and 75% of particles in the .3-1 µm range.
Understanding Microns
A single strand of the finest human hair is approximately 20 micrometers, or microns, in diameter. If you would slice that strand in half and then slice one
of those halves in half...and then one more time, you are left with a strand that is 2.5 microns in diameter. As you can see in the chart below, there are three different ratings depending on the micron size and as you learned above, those particles are extremely tiny. The
