PTFE finished parts
PTFE wedge ring packings
This robust and reliable packing is suitable for sealing valve shafts at high pressures and with abrasive media. The wedge rings are extruded inwards against the shafts and outward against the housing by the pressure of the stuffing box. The stuffing box follower can only be pre-stressed far enough to reliably seal the packing.
Piston rings and piston guide rings
Today's industry is increasingly in need of compressors that guarantee lubricant-free gas-tight sealing. In applications requiring the compression of dry gases a compressor at high temperatures and piston speeds, equipping the plant with PTFE piston rings is the design engineer's only option.
V-ring packings are primarily used for sealing with axial movements. A complete set consists of several V-rings with one pressure and support ring each.
For applications where the use of O-rings made from elastomers is not suitable - whether as a result of chemical attack or excessive temperatures - O-rings made of PTFE are used instead.
PTFE Support rings (Back-up rings)
The task of the PTFE support ring is to back-up the constant gap between the pistons and the cylinder.
The installation of support rings prevents the extrusion of the rubber O-rings into the sealing gap at axial movements to pressures over approx. 2.5 N/mm², leading to the destruction of the CD-ring.
PTFE enveloped O-rings unify the superior chemical resistance and low friction of PTFE and the elasticity of O-rings made from elastomers.
