Accessing the Application

Understanding your application is the key to proper selection of a connection. Use the following checklist to simplify your selection. 

Temperature:

Know your minimum and maximum temperature range.
 

Pressure:

 

What is the maximum pressure your connection will need to withstand during opertation? Will the connection need to operate under vacuum.
 

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:
 

Type: Hose barb, compression fittings, and push-to-connect are the most common termination styles.
Size: 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.
