The profile HPI double-acting piston sealing

set consists of an elastomer sealing component, two

antiextrusion and two angular guide rings.

Technical parameter:

Working pressure: ≤ 30MPa

Working temperature: -30℃~ +100℃

Surface speed: ≤ 0.5m/s

Working medium: Hydraulic oils (mineral oil-based)

HFA, HFB and HFC

Materials:

Rubber component: High wear resistance NBR with

ShA 80 hardness

Support rings: Reinfoced PA

Guide rings: Angular profile, modified POM

Advantages:

Sealing and guiding function with one complete set

Simple snap installation of the seal

Simple, short-fitting,one-part piston

Special design prevents distortion inside the groove

during installation

Installation:

Sharp edges and burrs in the assembly area must

be removed. Assembly is performed in the sequence

of rubber seal - support rings - angular guide rings.

Ensure that the contact point (gaps) of the angular

guide and anti-support rings are aranged in staggering

positions.
