PISTON SEAL KT1

STANDARD SEAL DIMENSIONS

DESCRIPTION

The KT1 compact seal is made of a central unit in NBR working as a seal, two side supports, working as anti-extrusion ring, and two external guide rings, keeping aligned the piston in the cylinder.

TECHNICAL DATA

Pressure: from 0 to 300 bar with peaks till 400 bar at 60°C
Speed: < 0.5 m/s Temperature: from - 30 °C at +100 °C Fluids: Mineral oils

MATERIAL

The compounds used to manufacture this seal type are the following:
• The central units is made of NBR, the hardness is
70 Shore A ± 3
• The sides support are made of a thermoplastic elastomer (TPE)
• The external wear rings are made of polyacetalic resin (POM)

ASSEMBLING

assembling of this seal can be carried out in either closed groove in a mono-block piston, or in open groove in a two-parts piston. The assembling has to be done as follows:
• Rubber element;
• Supports;
• Wear rings.
Avoid machining scores on the piston which may damage the rubber unit during the installation.
