Seal Clearance Reductions: What You Need To Know

Sealing and gaskets play an important role in protecting mechanical components from the elements, debris, and other contaminants. By understanding the different types of sealants and how they work, you can make informed decisions about choosing the right one for your application. In this article, we’ll look at how seal clearance reductions (SCR) can impact a machine’s performance, and provide tips on choosing the right SCR for your application.

What is a Seal Clearance Reduction?

Seal clearance reductions are a common practice in the shipping and manufacturing industries. They allow companies to reduce the number of required inspections on shipments by inspecting only those parts of the shipment that pose a high risk of defect.

The benefits of seal clearance reductions are clear: reduced costs, fewer delays, and improved quality. However, before implementing a seal clearance reduction program, companies need to understand the implications. Here are five key factors to consider:

1. What types of risks are we tolerating?

2. How do we know if a part is high-risk?

3. What is our tolerance for defects?

4. How much effort will it take to implement the seal clearance reduction program?

5. What impact will this have on our overall inspection process?

How Does a Seal Clearance Reduction Work?

When you are looking to reduce the clearance on a part, you have a few options. One is to reduce the size of the part. This is done by milling or grinding away material until the clearance is below the minimum required by the design. 

One alternative is to use a sealant or coating to reduce clearance. Sealants and coatings can be applied as part of the manufacturing process or after the part has been manufactured. 

A third option is to change the design of the part so that it does not require a full clearance. This can be done by reducing the size of components, adding features that lower clearance requirements, or using an intermediate component that reduces clearance requirements.

Why Would I Need a Seal Clearance Reduction?

A seal clearance reduction is a type of alteration that can be performed on a product to make it compliant with specific safety or environmental regulations. This alteration can be done in the manufacturing process, at the point of sale, or even after the product has been sold. Because seal clearance reductions are often specific to a certain regulatory requirement and require specialized knowledge and equipment, they are usually not done by general contractors or home improvement stores. 

The most common types of seal clearance reductions are those that make a product compliant with DOT regulations for transportation equipment, including trucks and trailers; CPSC regulations for children’s products; and EPA regulations for commercial equipment, such as industrial boilers and air conditioners. In each case, the alteration involves making modifications to the product that reduce its potential to release hazardous fumes or pollutants. 

There are a number of reasons why someone might need a seal clearance reduction. For example, if you own a commercial trucking company, you might need to make your vehicles compliant with DOT regulations so that they can transport cargo safely. Or maybe you’re an owner of a child’s car seat manufacturer and you need to make sure your products meet all the safety standards set by CPSC. 

Whatever the reason, it’s important to know what kind of alterations are required in order to comply with applicable safety and environmental regulations. That’s where a qualified professional like an engineer comes in handy. They can recommend the appropriate alterations based on the specifics of your product and the

Who Can Perform a Seal Clearance Reduction?

If you need to clear a seal on your property, there are certain requirements that must be met. The sealer must have the proper licensing and certification, and they must follow all safety guidelines. Additionally, you will need to provide them with all of the necessary information, including the address of the property being sealed. Finally, they will need to complete a clearance reduction assessment in order to determine if any repairs or modifications are necessary before the seal can be cleared.


Seal clearance reductions are an excellent opportunity to purchase items that you may have been unable to before. By taking advantage of these deals, you can save money on a wide variety of products, from household cleaners to electronics. Keep in mind that not all seal clearance reductions are the same; it is important to read the fine print before making any purchases. Be sure to also compare prices online so that you get the best deal possible.
