• Red Shield - A distinctive red stainless steel shield easily identifies MIFAB’s heavy duty MI-XHUB no hub couplings. Mechanical Interlocking Clamp Design - A one piece stainless steel screw housing mechanically interlocks the housing to the stainless steel band. This one piece housing eliminates leak paths that can develop with welded or staked clamps. Floating Eyelet Design - The stainless steel clamp bands can move independently from the corrugated stainless steel shield. This independence prevents the shield from crimping during tightening which can lead to leaks. 3/8” Hex Head Screw - The stainless steel 3/8” hex head screw is engineered to accept 80-inch pounds of installation torque to ensure a secure band / shield assembly around the pipe / fittings. Formed Gasket Design - The gasket is designed to form fit around the pipe and the inside of the shield so that when the clamping forces are applied, a superior sealing pressure and holding power is achieved. MIFAB’s gaskets are made from neoprene which meets the requirements of ASTM C564.

MIFAB® Series MI-HUB (specify size) shielded no hub couplings are manufactured with gaskets made from neoprene that meets the requirements of ASTM C-564 housed inside a Type 301 stainless steel corrugated shield. Two (2" through 4" size), four (6" through 10" size) or six (12" and 15" sizes) Type 301 stainless steel clamps tightened with 5/16" Type 305 stainless steel hex head screws surround the shield to provide the sealing force. MI-HUB Series Couplings are tested and certified to the ASTM-#C1277-2018, CISPI 310-2010, CSA B602-2016 (File # 247608) and B70 Standards. They are listed with IAPMO and NSF certified to CISPI 310. Also tested and certified by Intertek Testing Services to CAN/ULC S102.2-07 "Smoke Test."
