NORMA Group introduces the new V2-XC Quick Connector developed to deal with increasing demands in heavy duty applications (e.g. commercial vehicles, passenger vehicles, agricultural equipment and off-road equipment) and extended lifetime requirements. The more robust locking/unlocking concept makes it a pioneering innovation on the market.
Tighter emission controls call for reduced fuel consumption and improved efficiency. Despite these tough challenges, heavy-duty vehicles are still expected to deliver excellent performance. This means heavier engine loads, which in turn mean increased temperatures and pressures in media-carrying lines. The new V2-XC Quick Connector was made to meet these extreme conditions.
• Fast assembly without tools
• Long lifetime due to robust design
• Resistance to high temperatures
• Compact dimensions
• Integrated seal
• Seals can be visually checked

The V3® is designed for coolant vent lines. To guarantee that the product can resist cooling-water, the V3® is made two-parted. The housing is made of materials resistant to cooling water, and the locking ring is made of flexible material.
• Simple design
• Cost effective and reliable
• No assembly or disassembly tool required
• Anti-rotation feature

MK connectors have primarily been developed to reduce permeation rates. Compared with standard connectors that are prone to high permeation rates and constant micro leakage, MK provides the perfect link between the tank and the pipe system. The MK is not a standard part. All projects are based on specific customer requirements. We are therefore pleased to receive a description of your application in order to offer you an optimal, customized solution.
• Competitive price
• Can offer the complete solution and knowledge
• Full in-house production – we produce the entire system on our own from connectors to fuel lines to multi-layer lines
• Easy assembly
• Low permeation rate
• LET tube key component meets high requirement for a competitive price
• Reduces weight
• State-of-the-art lab to test products on request
• Conductive PA is possible

The TWIST II was brought to the market to connect plastic air intake or cooling system pipes in order to get leak-proof connections. By using the TWIST connector system, you can combine your design with plastic, aluminum or steel tubes. Flexibility and freedom of design are key words when systems with integrated TWIST connectors are engineered. TWIST connectors are engineered, eliminating leakages and helping reduce weight.
• Can be integrated in end-tanks as well as mounted on tubes or hoses
• A secure seal to the mating spigot with a low assembly force
• Robust and clear locking features with a click function to ensure a correct lock
• Easy operation for disassembly
• Temperature resistance of up to 180°C

TWIST III is a quick connector series for charged air system applications. Developed to meet extremely tough requirements, especially in low-emission vehicles, it combines a low assembly effort with very good hydrolysis tolerance, temperature resistance and mechanical performance. TWIST III operates at approx. 3.5 bar excess pressure and engine compartment temperatures of –48°C up to +135°C. Standard design configurations, 90° and adaptors. Special designs are also available.
• Compact design – space savings
• Always in “closed” position
• Easy open – no tool needed

PS3 “Push & Seal” plastic quick connectors are an ideal means for the secure connection of charged air systems to be used in pre-assembled systems.
• Can be mounted on a radiator or spigot
• Easy + secure seal to spigot
• Turbocharger to increase performance (e.g. high temperature)
• Click function for secure lock
• Easily disassembled
• Temp can reach 175°C
• To be used in pre-assembled systems
