Plungers

There are three different pistons to meet your application needs: A micro-interference fitting P-piston, a low friction piston (LF), and a non-interference fitting piston (NI). 

The higher the interference, the cleaner the wiping action on the inner diameter of the syringe barrel. However, this increases the potential for air-entrapment. You may want to sample a variety of pistons to find the right product for your material and application. Each piston is moulded from polyethylene and meets the rigid requirements of high tech industries.

These pistons are used in conjunction with additional Semco® products including syringes, caps and needles and tips.
