MAGNAPLAST low-noise 67° branch connector Ultra dB model 146595 for drainage and wastewater systems

The MAGNAPLAST low-noise 67° branch connector Ultra dB model 146595 is a purpose-built plumbing fitting for drainage and wastewater systems. It joins a lateral outlet to a main run at a 67-degree angle and incorporates sound-dampening construction to lower noise transmission from flowing wastewater. The fitting is designed for installation in residential and commercial sewer and drainage networks where reduced operational noise is desirable while maintaining standard hydraulic performance.

Advantages

The connector’s acoustic design reduces vibration and airborne noise compared with standard branch fittings, improving overall sound performance of the drainage installation. Its 67° branch angle provides a smooth directional change that supports efficient flow and reduces the risk of sediment accumulation. The component is compatible with common drainage pipe systems and is engineered for reliable joining and long-term service in typical wastewater environments.

Suitable for

• Residential drainage and building wastewater stacks
• Commercial sanitary and drainage systems in offices or public buildings
• Installations where lower noise transmission from wastewater flow is required
• Renovation and new-construction plumbing projects requiring a 67° lateral connection

Key specifications

• Branch angle: 67°
• Acoustic feature: sound-dampening construction for reduced noise transmission
• Application: drainage and wastewater systems
• Compatibility: designed for connection with standard drainage pipe systems
• Typical installation environment: indoor building drainage and sewer networks

How to use

Prepare the main run and lateral pipe ends according to the pipe manufacturer’s cutting and cleaning guidelines. Fit the MAGNAPLAST branch connector onto the prepared pipe ends, ensuring correct alignment at the 67° angle and full insertion of the pipe into the socket or joint. Use the recommended sealing method and couplings specified for the pipe system in use, and verify the connection for correct seating and sealing before pressure testing or backfilling. Follow applicable codes and installation instructions provided by the pipe and sealing system manufacturers.

Usage recommendations

Inspect sealing elements and pipe ends for damage before installation, and perform an acoustic-sensitive routing of vertical stacks away from noise-sensitive rooms when possible. For optimal noise reduction, combine the low-noise branch connector with other acoustic-rated drainage components and follow local plumbing standards for support, spacing, and testing.
