The oil and abrasion resistant NBR pneumatic o tube can be inflated up to 200 PSI against the outside diameter of the connecting pipe, speeding field set up and eliminating the need for low pressure flanged connections.Â
1) Low requirement to centered when installed, to achieve quick install and seal. .Â
2) The pipebe removed without other tools after pneumatic union deflated, adaptable and easy maintenance.Â
