RD40x1/7" NATO - 22M DAR adapter

RD40x1/7" NATO - 22M DAR adapter

Description

Adapter for a NATO standard (EN 148-1:1999) masks to attach bacteria/virus DAR filter with 22M connector. It is a remix of the product with added another collar to better seal the connection between the adapter and filter - version 6 for the best seal and easy of attach/detach. This version is modified to not use the support. It is tested by polish rescue teams members. Any suggestion for modification is welcome. Thanks, Enjoy!
