Certified to CSA B602 and listed to CAN/ULC S102.2 our MJ Grey mechanical couplings are available in 8”, 10” and 12” configurations for System 15 or System XFR. On large diameter joints, mechanical couplings are a great alternative to solvent cementing when working in cold weather conditions or from heights in a scissor lift or bucket. Relief is also available when you need to make an installation adjustment as our MJ’s can be adjusted in-field as required.
