​New Flange Construction


Introducing our one piece spun flange. Reduce leakage and labor installation costs with this improved gasketed mounting flange. It is available in both straight and conical fitting styles. See the individual data sheets for more information.​




It is our continuing goal to provide innovative products and improvements to better serve the HVAC and Industrial Hose industry.


We have recently developed and introduced our new

"Smooth-Lock"   manufacturing process.


This new manufacturing method removes the small internal edge of fabric that until now, is inherent to mechanical lock products. The resulting smooth internal surface improves system performance, reduces friction loss and saves energy. The strength

and the integrity of the mechanical lock plus reduced friction loss -

A Winning combination !
