Pump Fittings and Adapters

Find pump fittings, hose barbs, and adapters to connect tubing, filter housings, and process lines without leaks or cross-contamination. The collection includes sanitary tri-clamp elbows, mini flange to barb fittings, Luer barbs, aseptic and valved hose barb connectors, platinum-cured silicone pump tubing, and polypropylene filter housings. Brands include Saint-Gobain, Nordson Medical, Fisherbrand, CPC, Watson-Marlow, and Cole-Parmer. Before ordering, check the connection standard, barb ID, and wetted material (polypropylene, alloy C-276, silicone) in each listing to confirm chemical and sterilization compatibility. When fittings are used on a peristaltic drive, make sure tubing size matches your pump heads as well. Many items are offered in multi-piece lots, which suits labs that maintain several lines. Complete drives and systems are available in medical and lab pumps.
