Pistons  ensure that the pressure is evenly spread across the fluid
surface to  provide consistent dispensing.  Wiper seal pistons prevent
dripping and  eliminate material waste by wiping the syringe barrel wall
clean as  fluid is dispensed. Maximum operating pressure is 100psi
(6.9bar).


            "Easy Flow" Pistons (blue) are recommended for most
general  applications and they ensure no material residue is left on the
syringe  barrel walls while dispensing.

            Wiper Pistons (white) are a tighter fit for use with very
low viscosity fluid or with mechanical devices such as the TS700 manual
 syringe gun to prevent leakage past the double wiping edges.
Straight Wall Pistons (red) are recommended for reduced stringing and "bouncing" with high viscosity products.

700 系列点胶活塞
活塞确保针筒内压力均匀地散布在流体的表面 ，即使
是 高粘度材料也可实现稳定出胶。易流动活塞(蓝色)需
要较低的气压进行点胶，在点胶过程中可预防 空气陷
入。紧配合刮刀活塞 (白色) 对低粘度流体实现完全密
封。 松配合直壁活塞 (红色)可以在点高粘度流体时预
防垂涎以及活塞回弹。提供1000个大包装或者50个小包
装。活塞材质是聚乙烯（PE）
