400-series Quick Coupler
Optimized compressed air connectors
Designed for high airflow, low pressure drop, and long durability.
When only the best is good enough for your air tools, JWL’s 400-series couplings are the obvious choice. With outstanding airflow, low pressure drop, high durability, and ease of use, these couplings ensure maximum performance and efficiency. Additionally, the airtight construction guarantees economic and environmental benefits, while customization options and Danish quality make them the ideal choice—not only for professionals but also for OEM customers seeking tailored solutions.
5 good reasons to choose the new 400-series Quick Coupler:
High airflow
› 400-series Quick Couplers
Significantly better airflow than standard couplings – up to 200% better for EURO. No flow reduction or disturbances during connection. The optimized profile ensures maximum airflow and a secure connection without play or leaks.
Low pressure drop
› 400-series Quick Couplers
The low pressure drop through JWL couplings translates to improved efficiency, cost savings, enhanced tool performance, and reduced production time for you.
Durable
› 400-series Quick Couplers
Produced from high quality and long-lasting materials. Constructed to withstand the rigors of heavy-duty use and resist wear and tear.
Ease of use
› 400-series Quick Couplers
Straightforward and intuitive to use – one-handed operation in a single movement. Just insert the tool to connect and pull the sleeve-ring to disconnect.
Airtight
› 400-series Quick Couplers
Pressed together and U-cup sealing instead of screwed and O-rings. Airtightness affects both the environmental and economic aspects.
Calculation of the economic consequence of an ø1mm air leak: 0.7kWh x 0,34 Euro x 24h x 365 days = 2.085 Euro per year
…and several more for the “OEM”-buyer:
Compatible
Versatile range both in terms of profiles and connectivity options available. This eliminates the need for reduction nipples, sockets, and adaptors.
Customizable
The sleeve-ring can be custom printed with logo and color and laser engraved with part number etc. at the top.
Packaging options
For packaging we have several options ranging from bulk packaging with simple box labelling to single-packed couplers in customized bags in boxes with full colour labelling.
Made in Denmark
Designed and made in Denmark. We regard it as a seal of high quality
ISO 9001:2015
JWL is ISO 9001:2015 certified and all couplings are manufactured to the same high standard.
Harmless materials
Designed to comply with the environmental requirements of both European REACH and American Proposition 65. For example, lead alloy steel is replaced as far as possible with sulfur alloy.
