It also has a lower compression resistance; excellent resistance to water, alcohols, mild acids and mild bases; is non-corrosive; considered a non-irritant for "appraisal of the safety of chemicals in food, drugs and cosmetics"; and can be applied for LEED credit. The pink color is highly visible for easy inspection on the job site while of course furthering the awareness of the need to join the fight against breast cancer.

The mission of the Breast Cancer Research Foundation (BCRF) is to prevent and cure breast cancer by advancing the world's most promising research. To help further the cause of the BCRF, Duro Dyne decided to partner with them and hold a machinery auction in 2017 which resulted in $65,885 being raised for Breast Cancer Research.

Duro Dyne is continuing its fundraising partnership with the Breast Cancer Research Foundation by contributing $2 to the BCRF for every box (500 ft) of Pink Butyl Gasket sold.

Dual Dyn-O-Claw

Working in conjunction with Dyn-O-Mate Rod Locks and conduit, the Dual Dyn-O-Claw creates an effective duct strengthening system and are easier and faster than other alternatives such as ties or welding. The Dual Dyn-O-Claw works for both 1/2in and 3/4in conduit.
