PP Double Branch in Two Planes 67°

  Datasheet (PDF)

The PP double branch in two planes HTDA 67° d110mm is an injection-moulded polypropylene fitting designed for soil, waste discharge, and internal ventilation stacks within residential, commercial, and industrial buildings. Featuring a 110 mm nominal diameter with two 67-degree branches arranged in perpendicular planes, this fitting enables dual branch inflows into a single vertical stack. Push-fit socket ends with factory-fitted EPDM lip gaskets ensure rapid, secure jointing without chemical solvents.

Technical specifications

The HTDA double branch in two planes provides reliable structural rigidity and smooth hydraulic flow for multi-directional drainage connections. Its precision-moulded geometry avoids abrupt transitions, preventing solid accumulation and minimizing blockages in gravity networks.

• Nominal fitting diameter: 110 mm with dual 67-degree lateral branch entries oriented across two planes
• Thermal performance: 60 degrees C continuous operating temperature, up to 95 degrees C for short periods, and impact resistant down to -15 degrees C
• Chemical compatibility: Resistant to acidic and basic domestic and industrial effluents across a pH range from 2 to 12
• Hydraulic efficiency: Manning roughness coefficient of 0.01 for smooth discharge and minimal flow friction
• Sealing interface: Integrated factory-installed EPDM elastomeric lip gaskets for tight push-fit connections
• Operational lifespan: Estimated minimum service life of 50 years under standard operating conditions

Materials and standards

Manufactured from stabilized unplasticized polypropylene (PP), the fitting features high chemical resistance to caustic agents, aggressive salts, and laundry or dishwasher detergents. Polypropylene offers superior dimensional stability, an elasticity modulus of 1300 N/mm², and a raw material density of 0.95 g/cm³.

The branch is produced in compliance with SR EN 1451-1 and standard SF98/2017. In shock resistance assessments conducted according to SR EN 744, the material exhibits zero percent breakage, maintaining structural integrity during cold-weather handling and installation.

Installation and jointing

Assembly relies on manual push-fit socket connections with factory-seated EPDM gaskets, entirely excluding the use of solvent adhesives or open flame heating. The elastomeric gasket absorbs axial movements and minor building vibrations, functioning as an integrated expansion buffer.

Before jointing, verify that the gasket groove is clean and apply a dedicated pipe lubricant to both the gasket and the chamfered spigot end. Shortening or cutting the fitting is strictly prohibited to preserve connection security. When connecting straight pipes into the branch sockets, push the spigot fully home, mark it, and withdraw it by 10 mm to accommodate thermal expansion; this withdrawal step is omitted for direct fitting-to-fitting connections.
