- Piston seal- DK 142
Pistn seal DK142 profile is a cap seal with anti-extrusion, low friction and low wear features. It is a bi-directional piston seal for use in low to medium duty applications. Because of the unique design of the filled PTFE cap, the DK143 profile offers long wear, low friction and anti-extrusion. Only minimal gland space is needed to fit the seal on the piston due to its short assembly length.
