Euro standard Series 20 Super mini type pneumatic quick couplings with internationally used profile

Euro standard Series 20 Super mini type pneumatic quick couplings with internationally used profile

Precision-Engineered for High Performance in Compact Pneumatic Systems

Product Overview

The 20 Series European Style Pneumatic Quick Connect Couplings are designed for applications where space savings, high flow efficiency, and reliable performance are critical. With a compact design and compliance with European standards (e.g., EURO 2.7), these couplings typically feature a 2.7mm bore diameter and support flow rates up to 130 L/min at 6 bar. Their ergonomic design allows for easy one-handed operation, making them ideal for precision pneumatic tools, medical equipment, automation systems, and compact industrial machinery.

Key Features

1. Compact Design & High Flow:

• 2.7mm bore diameter minimizes pressure drop in a small form factor.

• Flow rates up to 130-165 L/min ensure efficient operation in compact systems.

2. Robust Construction & Materials:

• Brass body with nickel plating offers excellent corrosion resistance. Some variants also available in stainless steel or carbon steel.

• NBR (Nitrile Rubber) seals provide a reliable leak-free connection and perform within a temperature range of -20°C to +80°C (up to +100°C for some models).

• Maximum operating pressure typically 35 bar (507 PSI).

3. Safety & Interchangeability:

• Many models feature a single shut-off valve mechanism.

• Designed for interchangeability with major European brand profiles like Rectus 20/91, Legris 20, Festo 20, Walther 06-003, Bosch Size 1, and Norgren 232.

• Complies with relevant industry standards (e.g., ISO 6150-B).

4. Ease of Use:

• Ergonomic, often knurled sleeve design allows for single-handed coupling and decoupling, even with gloves.

5. Connection Variety:

• Available in various connection types including BSPP (G), BSPT (R), NPT, and hose barb configurations (e.g., 4mm, 6mm, 1/8", 1/4").

FAQ

Q: Are your 20 Series couplings compatible with Rectus 20 series?
A: Yes. Our 20 Series couplings are designed to be fully interchangeable with Rectus 20/91 series and other listed European profiles.

Q: What is the maximum pressure rating for the standard 20 Series?
A: The maximum operating pressure is typically 35 bar (507 PSI) for standard models.

Q: What materials are available for the body and seals?
A: The body is commonly nickel-plated brass. Stainless steel and carbon steel are also options for some models. Standard seals are NBR (Nitrile Rubber), suitable for general use with air and many fluids.

Q: Do you provide certifications?
A: Our couplings are manufactured to meet industry standards such as those related to ISO 6150-B2. Specific certifications can be discussed upon request.
