Quick-disconnect couplings

Product catalog summary

1. Overview

This document details technical specifications, design features, and application guidelines for various quick couplings used in medical, biological, chemical, food, pneumatic, and industrial fluid systems. The couplings are primarily made from PVDF, brass, stainless steel, and feature safety, sterilizability, and ease of use.

2. Product Range and Materials

Materials: PVDF bodies and safety elements, brass, stainless steel; seals made from EPDM/FDA, Viton, Kalrez, Perbunan N, and FPM (Viton).
Special Features: Pre-coated threads with Loctite 5061, degreasing cleaning, glass or PTFE locking balls, silicone membranes for sampling, titanium springs for self-closing valves, stainless steel springs and balls for durability.
Sizes: Nominal diameters range from DN 2.7 mm to DN 24 mm, with common sizes DN 10 mm (3/8") and DN 12 mm (1/2").
Color Coding: Blue, red, and natural (white) for easy identification and prevention of cross-contamination.

3. Technical Specifications

Nominal Pressure: Up to 10 bar at 20°C for PVDF couplings; up to 35 bar for brass/steel series.
Operating Temperature: -40°C to +120°C for PVDF (sterilizable up to 150-160°C); -40°C to +200°C for stainless steel Viton-sealed couplings.
Compatibility: DIN/ISO 58352 nipple profiles; interchangeable with common competitive products in pneumatic series.
Flow Capacity: Kv values range from approximately 220 l/h to 7800 l/h for PVDF couplings; airflow rates from 280 to 1400 NI/min at 1 bar differential for pneumatic series.

4. Coupling Functions and Types

Valve Options: Double-sided shut-off (both coupler and nipple with valves), one-sided shut-off (coupler with valve, nipple without), and free passage (no valves).
Connection Types: Female and male threads, hose nipples, SERTO unions, panel mounting, and tube connections.
Operation: Designed for quick, one-handed, tool-free operation with detachable hose connections and clear color markings.

5. Product Series and Variants

PVDF Quick Couplings: Emphasize chemical resistance, sterilizability, and safety for medical and food applications.
Brass/Steel Pneumatic Series (20, 21, 22): Miniature to standard air-line couplings with nominal sizes from 2.7 to 24 mm², operating pressures up to 35 bar, and airflow rates from 280 to 1400 NI/min.
SERTO Stainless Steel Series (20E, 21E): High corrosion resistance, Viton seals, operating temperatures up to 200°C, suitable for demanding chemical and medical environments.

6. Ordering and Customization

Ordering codes specify coupling type (valve presence), nominal diameter, connection type, and optional features such as stainless steel locking or sampling membranes.
Special options include HOSPAL machine compatibility and customized membrane or valve configurations.
Some items are available on request and not stocked regularly.

7. Applications

Suitable for liquids, gases, vacuum, and drinking water in laboratories, medical technology, dialysis, biological and chemical processes, food industry, pneumatic systems, measurement and control lines, miniature pneumatic tools, spray devices, and cooling lines.

8. Key Recommendations and Best Practices

Select coupling configuration based on required shut-off function and connection type.
Use color coding to prevent cross-contamination and ensure correct assembly.
Choose seals and membranes appropriate for chemical compatibility and sampling needs.
Ensure proper thread sealing using pre-coated threads with Loctite 5061.
Strictly adhere to temperature and pressure limits to maintain safety and performance.
Consider stainless steel and Viton seals for enhanced chemical resistance and higher temperature tolerance.
One-handed, tool-free operation enhances safety and ease during connection/disconnection under pressure.
