Semco® Red Hybrid Syringe Wiper Piston

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.
