Non-Drip Quick Connect Couplings

Product catalog summary

Introduction
CEJN is a leader in designing and manufacturing quick connect couplings for pneumatic, hydraulic, and fluid systems. Their non-drip couplings are tailored for low-pressure fluid and vacuum applications, featuring modular construction and non-drip capabilities to enhance safety and performance.

Product Features

Modular Construction: Standardized dimensions for components allow easy interchangeability and diverse configurations.
Non-Drip Design: Minimizes spillage, reducing risks of injury or damage during connections.

Safety Levels
CEJN provides three safety levels for couplings and nipples:

Level 1 - Standard: Basic compatibility within the range.
Level 2 - Color Coding: Uses color-coded rings for media and pressure line identification.
Level 3 - Key Coding: Non-interchangeable keys prevent cross-connection, with color coding for identification. Optional safety-locking devices are available to prevent accidental disconnection.

Technical Specifications
Couplings come in various sizes and materials, such as nickel-plated brass and stainless steel, supporting pressures up to 20 bar (290 PSI) and temperatures up to 315°C (600°F). Options include single shutoff, double shutoff, and straight-through configurations.

Flow Capacity and Materials
Flow capacity is assessed at a 4 bar pressure drop. Seal materials like NBR, FPM, EPDM, and Kalrez are available to meet specific needs.

Conclusion
CEJN's non-drip modular couplings provide versatile, high-performance solutions for low-pressure fluid applications, ensuring safe and spill-free connections.

Overview
The document details standard female threads and their compatibility with various adapters and thread standards, including male-to-male and male-to-hose adapters in brass and stainless steel, with optional dust caps for all sizes.

Specifications
Thread sizes for brass and stainless steel materials include:

Brass: Male G and NPT threads from 1/4" to 1" and hose connections from 1/4" to 1".
Stainless Steel (AiSi 316): Similar range as brass, with Male G, NPT, and hose connections.

Components
Adapters and dust caps are highlighted for maintaining connection integrity and cleanliness.

Manufacturer Information
CEJN AB, based in Skövde, Sweden, specializes in quick connect solutions.

4 When CEJN engineers sat down and began to brainstorm just what would make a non-drip coupling design a sought-after product, they determined that the new range would need to have almost endless combination possibilities for almost endless applications. And that is exactly what the series offers as a result of its modular styling. Since each coupling is compatible with each nipple in the series, customers can be ensured of just the right configuration for their specific applications by selecting from a wide range of standard products. The off-the-shelf products eliminate time previously spent...
