Piston seal HPCO

DESCRIPTION
HPCO is a compact sealing profile energized by an O-ring and designed for bidirectional sealing in hydraulic and pneumatic systems. It combines low friction, good pressure response and high resistance to wear.
ASSEMBLY
Install HPCO in a clean housing free from sharp edges and burrs, observing the specified radii, lead-in chamfers and surface finishes. Lightly lubricate the seal and avoid twisting or damage. During maintenance, check for leakage, wear and housing condition.
ADVANTAGES
MATERIALS
HPCO can be manufactured with a 60 Shore D filled PTFE sealing ring and a 70 Shore A NBR, FKM or EPDM energizing O-ring. Selection depends on the medium, temperature, pressure and lubrication.

TECHNICAL DRAWING AND INSTALLATION PARAMETERS FOR THE HPCO PISTON SEAL

This technical diagram sets out the dimensions and geometric parameters needed to select and install the HPCO piston seal correctly, a compact assembly consisting of a symmetrical-section PTFE sealing ring and an energising O-ring housed inside it. It shows the dimensions linked to the size table, the outside diameter (ØD), the groove root diameter (Ød) and the groove width (B), together with the radial clearance between piston and bore (S), which governs the risk of extrusion as pressure rises. The table completes this data with the O-ring matching each reference, given by its inside diameter and its cord section. The housing must be clean and free from sharp edges and burrs, with radii, chamfers and surface finish within specification. Meeting these dimensions ensures correct O-ring pre-load, twist-free installation and stable sealing performance in diameters from 6 to 2000 mm.

THREE-DIMENSIONAL VIEW AND COMPONENTS OF THE HPCO PISTON SEAL

This 3D illustration shows the structure of the HPCO piston seal. As a two-piece assembly, it comprises a filled PTFE sealing ring at 60 Shore D, which wraps around the O-ring and runs against the cylinder bore, and an energising O-ring in NBR, FKM or EPDM at 70 Shore A, seated inside it. The O-ring does not run against the bore, its role is to hold the PTFE ring steadily against the sliding surface and to respond automatically to pressure variation. The ring section is symmetrical, which is why the assembly seals in both directions and why installation does not depend on the orientation of the part. This division of duties gives the profile its performance, the PTFE provides low friction, stick-slip free running and good resistance to wear and extrusion, and the elastomer provides the closing force required even at low pressure. The assembly withstands up to 35 MPa at speeds of up to 1.5 m/s and temperatures from -35 to 200 °C depending on the material selected.
