How to Make the Right Fitting Connections

After you’ve decided on the right pump, chromatography system, or fermentation equipment, you’ll want to make the right fitting connections. The wrong connections can cause leaks, unwanted flow restrictions, and costly downtime. To avoid these problems, choose your fittings correctly. Start by answering the following questions:

  1. What type of tubing are you using? Barbed fittings work best with flexible tubing such as silicone or PharMed® BPT. Compression fittings work well with rigid tubing such as PTFE or polypropylene.
  2. What is the material compatibility? Fluids that are incompatible with the fitting material may cause leakage or system damage. For highly corrosive fluids, PTFE is the best.
  3. What are your temperature and pressure conditions? Make sure you choose fittings rated for your operating conditions.

So, what type of fitting do you need? Review the features and benefits of each fitting type.

Check your material compatibility with our chemical compatibility database.
