    Assessing the Application

    Understanding your application is the key to proper selection of a connection.

    • Temperature : Know your minimum and maximum temperature range. Standard temperature tolerances range from -40°F to 200°F depending on connection material.
    • Pressure : What is the maximum pressure your connection will need to withstand during operation? Quick disconnects rated to 250 psi will handle most low-pressure applications.
    • Media: The viscosity and corrosiveness of the fluid going through the connection needs to be considered. Make sure the media is chemically compatible with all coupling materials - including the seals or "o-rings."
    • Shutoff Options: Do you need automatic or integral shutoff valves to prevent drips and spills? Shutoff options are single, double and non-spill.
    • Flow: What are your required gallons per minute (GPM) and pressure drop? Be sure to allow for the effect of shutoff valves and tubing connections on your calculations.
    • Tubing: What size tubing, both inner and outer diameter, are you using? Double check media compatibility.
    • Tubing Connections: Hose barb, compression fittings, and push-to-connect are the most common termination styles. You will need to know ID for hose barbs, OD for push-in-fittings, and tube ID and OD for compression.
    • Mounting Options : How is the connection going to be configured into your application? Common mounting options include pipe thread, panel mount, in-line or elbow.
    • Special Requirements: Sterilization, NSF listed, USP Class VI approved materials, special packaging, color coding, keying, lot traceability, etc.

    How to Choose the Right Connector

    Determining Connection Type

    Fittings, luers and couplings are the most common tubing connectors. While each is appropriate for certain types of applications, they are not necessarily interchangeable; it’s important to specify the connector that satisfies your specific application requirements.

    Material Options

    The type of media flowing through a connection can affect the strength, surface appearance, color and performance of the connection.

    O-Ring Selection

    Certain o-ring materials offer better chemical resistance while others offer better heat resistance or cold flexibility within your application. For specific chemical properties, refer to our Chemical Compatibility Guide.
