The male part of the high-end Koolance quick release coupling!
The new generation is specially designed for high-flow systems. These couplings have excellent quality and practicality, just as always from Koolance. The female and male parts are each equipped with a locking bolt which makes canting of the coupling impossible during separation and hence makes the seal much more reliable and safer.

When connected additionally a silicone seal will press against the inner wall of the female coupling which additionally seals the connection. To prevent unwanted separation the coupling is locked and released by twisting the coupling. Hence it cannot be separated until it is twisted back.
The other side of this connector is equipped with 10mm barbs for maximum compatibility!
Technical specifications:
Material: Nickel plated brass
Hose size compatibility: 10mm (3/8) inner diameter
Overall length: 52mm

Extent of delivery:
1x Koolance quick release coupling 10mm barbs (3/8) plug (High flow) – VL3N
Important note regarding use of the connectors:
To ensure a tight seal between coupling and plug the units are designed for a very tight fit. When repeatedly plugging the connectors in and out, this may lead to roughening of the O-ring or even tearing of the gasket. Hence the gaskets should always be kept moist when plugging the connection in or out!
Please note: Not entirely leak-free (meaning that after separation 1-2 drops may spill).
Overview:
10mm (3/8) hose clamp: up to 8mm none, from 10mm up required
10mm (7/16) hose clamp: up to 8mm none, from 10mm up required
12mm (1/2) hose clamp: up to 11mm none, from 12mm up required
13mm (1/2) hose clamp: up to 11mm none, from 13mm up required
Please note: Should you use different versions, such as VL3 to VL2 or VL3N to VL3, you may damage your O-rings, resulting in a leaky connection. Please also be careful to align the plug and coupling when inserting to avoid damage to the O-rings of the plug. If you damage your O-rings by improper handling it is not covered by the warranty!
