Thermo Scientific Nalgene* Barbed Bulkhead Fittings

To install, simple drill two 5/8 inch (16 mm) diameter holes in closure insert fittings, tighten, and attach tubing. Comes with complete directions and template for installation. Gasket and nut assemblies provide leakproof service. Can be sterilized by autoclave, gas or chemical methods.
