GF Silenta 3A PP Fittings – High-Performance Sound-Insulated Drainage Solutions

The GF Silenta 3A PP Fittings are designed to provide exceptional noise reduction, durability, and leak-proof performance for modern drainage systems. Made from PP-mineral reinforced composite, these fittings offer high impact resistance, easy installation, and fire safety, making them ideal for residential, commercial, and industrial applications.

Key Features and Benefits

 

Superior Sound Insulation

• Minimizes airborne and structure-borne noise.
• Achieves a low noise level of 16 dB(A) at 4 l/s (EN 14366).
• Ideal for noise-sensitive environments.

 

Durability and Strength

• Made from PP-mineral reinforced composite for high impact resistance.
• Resistant to corrosion, extreme temperatures (-10°C to 97°C), and chemicals (pH 2-12).
• Alternative to cast iron fittings, offering long service life.

 

Easy Installation and Leak-Proof Design

• Push-fit socket system with rubber gaskets for quick and secure connections.
• Lightweight structure reduces installation labor and costs.
• Anti-shrink system prevents deformation due to temperature changes.

 

Fire and Environmental Safety

• Flame-retardant properties classified as B2 (DIN 4102).
• Halogen-free and cadmium-free, preventing toxic gas emissions in case of fire.
• 100% recyclable, supporting sustainable construction practices.

Installation Guidelines

1. Prepare the Pipe and Fittings: Cut the pipe at a 90° angle, remove burrs, and clean the spigot end.
2. Apply Lubricant: Use a silicone-based lubricant on the spigot end for a smooth fit.
3. Insert the Fitting: Push the pipe into the socket until it reaches the marked depth.
4. Allow for Expansion: Pull back 10mm to account for thermal movement.
5. Secure the System: Use GF Hakan Silent Clamps to ensure stability and noise reduction.
