Quick Connectors

The easy-to-use Q Series Quick Connectors were designed for use with laboratory and portable test equipment, gauge calibration, sampling systems, biopharmaceutical applications, and gas distribution. Q, Keyed Q, and QF Series Quick Connectors are very easy to use. No tools are required to couple or uncouple Quick Connectors, and a minimum amount of equipment must be shut down. With Hy-Lok Quick Connectors, there is no possibility of over or under tightening, galling, or cross threading.

Quick Connector Specifications

Hy-Lok Quick Connector sizes range from 1/4” to 1” wide. They are rated for use in environments as cold as -10°F (-23°C) and as hot as 400°F (204°C). They can handle a working pressure of up to 6,000 psig (413bar).

Exact Quick Connector specifications vary based on series, model, material, and other factors. Be sure to check the specifications of the precise models that you are considering using.

Hy-Lok recommends that filters always be used with Quick Connectors, and that uncoupled Quick Connectors be protected with dust caps or body and stem protectors. Hanging hoses should be supported to prevent sideload. Stem seal O-rings should be lubricated regularly.

Coupling and uncoupling should always be performed during system cleaning and at room temperature. Be sure to keep body and stem aligned while coupling and uncoupling.

FAQs

What are quick connectors used for in fluid and gas systems?

Quick connectors are designed to allow fast and secure connections between fluid or gas lines without the need for tools. They enable operators to quickly couple and uncouple equipment while maintaining a reliable seal.

These connectors are commonly used in laboratory equipment, portable test systems, calibration equipment, sampling systems, gas distribution systems, and biopharmaceutical processing where systems must be connected and disconnected frequently.

What are the differences between the Q Series, Keyed Q Series, and QF Series quick connectors?

Hy Lok quick connectors are available in three primary product families designed to support different system requirements.

The Q Series connectors provide a versatile quick connect solution for general laboratory, instrumentation, and testing applications. The Keyed Q Series connectors include a keying feature that prevents incorrect connections between incompatible lines. The QF Series connectors are designed for applications that require higher flow capacity and robust performance in demanding environments.

Selecting the correct series depends on system pressure requirements, connection compatibility, and the specific application.

What pressure and temperature ranges can quick connectors handle?

Hy Lok quick connectors are engineered to perform in demanding operating conditions. Depending on the series and model, they can operate in temperatures ranging from negative 10 degrees Fahrenheit to 400 degrees Fahrenheit.

They are also capable of handling working pressures up to 6,000 psig or 413 bar. Exact performance specifications may vary depending on connector size, materials, and the selected model.

What maintenance practices help ensure reliable quick connector performance?

Proper installation and routine maintenance help ensure long term performance of quick connectors. Filters should be used to prevent debris from entering the system, and uncoupled connectors should be protected with dust caps or body and stem protectors.

It is also recommended to support hanging hoses to avoid sideload stress and to regularly lubricate stem seal O rings. Coupling and uncoupling should be performed during system cleaning and at room temperature while keeping the body and stem aligned to prevent damage.
