Air Seal Unions quickly connect and disconnect mud suction lines, return lines, and other low pressure fluid lines.  These unions provide a tight seal even if the pipe is not properly aligned (to certain limits).  Body is ASTM A216 Grade WCB carbon steel. The oil-resistant inflatable tube is heavy-duty and abrasion resistant. The tube design is for 200 psi maximum air pressure. (The tube inflation pressure must exceed fluid line pressure by 50 psi to properly seal the line pressure up to 150 psi).

Also available in a range of rubber compounds and materials to suit your application.
