Plastic Fittings - End Caps

Bio Cap


The Bio Cap is the only non-metallic cap with a built-in tab for quick removal, which reduces potential damage to sanitary flanges.

Bio Cap available in PP only.

The Bio Cap is the only non-metallic cap with a built-in tab for quick removal, which reduces potential damage to sanitary flanges.

The tab eliminates the tendency to use non-sanitary tools, including screwdrivers and pliers, to assist in cap removal. The cap is delivered with permanent size and lot number identification to ensure proper use and easy traceability.

   
Flat End Cap

The Flat End Cap has the same uses as the Bio Cap, but its designed without the built-in tab. Flat End Caps may also be modified to accept female threads and be integrated into dip tube fabrications.
