Mifab 3001-33 Shielded Transition Coupling 3 Inches

Product Description

The MIFAB 3001-33 is a 3-inch shielded transition coupling designed to join dissimilar or like pipe materials in drain, waste, and vent (DWV) piping systems. The shielded design provides full circumferential contact between the coupling body and pipe ends, creating a secure, leak-resistant joint without requiring solvent welding or soldering. At 0.52 pounds, this lightweight fitting is straightforward to handle and position during installation. Licensed plumbers and pipefitters typically specify shielded transition couplings when connecting pipes of different materials or where a no-hub style connection is required.

This coupling is suited for residential and light commercial plumbing applications where a 3-inch pipe connection is needed. It is commonly installed at transitions between cast iron, ABS, PVC, or other DWV pipe materials within above-ground drain, waste, and vent systems. The shielded body helps distribute clamp load evenly around the pipe circumference, which is particularly useful in retrofit and repair scenarios where pipe ends may not be perfectly uniform.

Key Features

• 3-inch nominal pipe size for standard DWV applications
• Shielded design distributes clamping load evenly across the pipe joint
• Lightweight at 0.52 pounds for easy single-hand positioning
• No-hub style connection eliminates need for solvent cement or soldering
• Suitable for transitions between dissimilar pipe materials in DWV systems

Compatibility

Designed as an OEM-style replacement and standard-use shielded transition coupling for 3-inch DWV piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water flow and ensure the system is depressurized before beginning work. Pipe ends should be cut square and deburred for proper coupling seating and a leak-free joint. Torque clamp bands to the coupling manufacturer specifications using a calibrated torque driver or nut driver.
