Quick Connectors
Cooling System
Innovative and secure, NORMA Group's wide range of quick connectors are easy-to-assemble plug-in connections across cooling systems in OEM industries. Our quick connector portfolio offers state-of-the-art connections, reducing permeation rates and helping reduce total system weight so important to today's OEM's. Made from synthetic material, NORMA's connectors are suitable for most media carrying lines.
SAE STYLE (SAE Quick Connector)
Specialized plastic quick connectors developed for coolant applications. Test parameters are significantly higher than operation parameters. Special applications possible, contact us!
• Media: Coolant
• Operating temperature: –40°C to 135°C, short term higher
• Pressures: 0 to 2 bar pos. pressure, partially pulsating (sinusoidal)
• Vibrations: Usually engine vibrations 7–200 Hz, 0.2–20 g
PS3
PS3 “Push & Seal” plastic quick connectors are an ideal means for the secure connection of cooling water and heating hoses.
• Locking function
• Simple spigot
• O-ring is on the inside to prevent damage to seal
• Series experience since 1997, volume experience of a total of 70 million PS3
• New optimized version with reduced weight can be offered
C STYLE (VDA Quick Connector)
Specialized plastic quick connectors developed for coolant applications. Test parameters are significantly higher than operation parameters. Special applications possible, contact us!
• Media: Coolant
• Operating temperature: –40°C to 135°C, short term higher
• Pressures: 0 to 2 bar pos. pressure, partially pulsating (sinusoidal)
• Vibrations: Usually engine vibrations 7–200 Hz, 0.2–20 g
V3
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. To ensure that you save space, the V3® only has a half locking ring and is designed with an anti-rotation feature.
TWIST II
TWIST II is a “Push & Seal” plastic quick connector; an ideal solution for connecting cooling water systems.
• 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
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. 2.75 bar excess pressure and engine compartment temperatures of -48°C up to +135°C. Standard design configurations are straight. Special designs are also available.
