WHAT IS A MAP SEAL?

Standard

A MAP Seal is the ONLY USDA Compliant Seal for your rotary valve on the market. Comprised of a PTFE Polymer Carrier and USDA Grade Silicone, the MAP Seal was engineered for ANY application.

Designed to handle temps from -62 to 350 Degrees F the MAP Seal is perfect for any process and valve location. Discover the only seal you'll ever need by downloading the .pdf below. 

HOW A MAP SEAL WORKS?

Take the possible 4-6 hours of downtime & extensive labor to replace an airlock seal, and cut it to less than 15 minutes!!

 

With Rotary Airlocks Proprietary Mechanical Aerated Polymer Seal System (MAP Seal) there is absolutely ZERO need to pull an airlock or strip off any end-caps.

 

You save time, labor, and lost profits. Simply disengage the MAPS Housing Cap to access the seal directly and replace the MAP Seal in-line quickly & efficiently, getting you back up and running as fast as possible.

...the MAP Sealing System has worked so well for our plant that our MD500 is working better than when it was new.
