MU Overcollars are one of the least expensive and fastest ways to make connections for small diameter spiral duct, according to officials with manufacturer Metu-Streimer.

HVAC construction contractors looking for a competitive edge find that saving money in field labor has the biggest impact on the bottom line.

The Metu-Streimer MU Overcollar is a great way to reduce field hours while delivering a top-quality spiral pipe connection, the company said. Some of the many benefits of using MU Overcollars are: 

• Economical connections
• Connections to terminal units
• No projections inside the duct
• One-bolt assembly
• Easily disassembled

Metu-Streimer stocks MU Overcollars in diameters from 3 inches to 16 inches.

The MUPE Overcollar has a polyethylene gasket that will seal the connection when installed. Overcollars are also available with an EPDM (ethylene propylene diene monomer) gasket.

 Metu-Streimer stocks MU Overcollars in diameters from 3 inches to 16 inches. The company says it also has a full line of spiral duct accessories including access doors, round MF flanges and joining clamps, and a complete line of duct hanging brackets.
