Cole-Parmer can provide quality tubing connectors and pipe fittings to help you set up your fluid handling system with no leaks, flow restrictions or costly downtime. Cole-Parmer’s tubing connector range includes barbed fittings for flexible tubing, compression fittings or pipe connectors for rigid tubing. Tubing connectors and pipe fittings are available in sizing to connect anything from microbore tubing up to pipes. We offer a variety of materials such as low cost polypropylene (PP) for general applications to PTFE for corrosive media, formulations that comply with FDA and USP regulations and for no extra charge we can offer certificates of fittings compliance our range in tubing connectors and pipe fittings.
Cole-Parmer provide you with the information you need to select an optimal fitting. We provide the basic physical property information including temperature and pressure rating for each material formulation. Our chemical resistance charts help determine the fitting material with best chemical compatibility to your process. Our selection includes:

Slides into flexible tubing. Tubing elasticity holds the tubing onto the fitting for low-pressure installations
- Sizing: microbore – 2” ID
- Available materials include: HDPE, Nylon, PP, Kynar, 316SS
Have a nut that compresses rigid tubing against the fitting body for high pressure applications
- Sizing: 1/16” to ¾” OD
- Available materials include: HDPE, Nylon, PP, Kynar, 316SS
Threaded in NPT (National Pipe Taper), UNF (Unified Find Thread) or BSP (British Standard
Pipe) sizes for permanent, high-pressure pipe connections
- Sizing: 1/8” to 1” NPT and BSP
- Available materials include: PP, Nylon, PTFE, 316 SS
Allow you to make and break tubing connections without separating tubing from fitting. Available
with barbed, pipe compression, and push-to-connect connections
- Available materials include: PP, brass, PTFE, Stainless Steel
