GFD Standard Type 414 PTFE Radial Seals

GFD Standard-Radial Seals

The GFD spring energized PTFE seal is the newest generation of spring actuated Teflon seals. These seals consist of a special precision jacket/lip made of Teflon (or other high performance polymers) and a corrosion resistant stainless steel spring.

In this combination, the spring is forcing the seal lips against the gland and the rod walls. The pressure assists the spring force.

The spring compensates the lip wear, hardware tolerances, eccentricities and provides permanent resilience to the seal lips. The GFD design with sealing lip and spring arrangement guarantees more leakage protection than conventional lip seals.

More than 50 different PTFE compounds (and other high performance polymers) are available or can be composed for jacket fabrication within a very short
time.

The standard designs cover radial and axial seals for dynamic as well as static applications. In addition to standard designs, we are also able to produce designs made to specification for special applications (silicone filled, sanitary seals, ultra low friction seals, etc.).

A wide variety of materials, dimensions, and designs provide the opportunity to solve difficult sealing problems.

Seal Selection and Operation Range
The wide variety of types provide the opportunity to meet all sealing requirements for axial and radial seals. Not all maximum stresses can be applied to the seal at one time.

The variety of designs,jacket and spring materials, together with several springs and dimensions allow sealing applications within the following working ranges:
Temperatures from -250°C to +316°C
For rotation and reciprocating movement up to 5 m/s
For static applications up to 3500 bar pressure
For dynamic applications up to 550 bar pressure
Universal chemical-resistant
For vacuum and UHV applications
Diameter from 2 mm up to 3000 mm

Material Description	Temperature Range Degrees [°C]
PTFE-virgin	-250...+205°C
Recommended for low to moderate dynamic or static service. Low gas permeability.
FDA approved. Good cryogenic (low temperature) properties.
PTFE-virgin modified	-250...+215°C
Recommended for low to moderate dynamic or static service. Lowest gas permeability.
FDA approved. Higher creep resistance, very high chemical resistance.
PTFE-reinforced with Carbon and Graphite	-130...+290°C
Very good universal properties for higher temperatures and resistance to wear.
Especially suitable for hot water and steam service as well as for poor lubrications.
PTFE-filled with Graphite	-130...+290°C
Excellent general purpose material with low friction, good wear and heat resistance.
Non-abrasive. Good for water service, dry or poorly lubricated applications.
PTFE- filled with Glass fiber and MoS2	-155...+290°C
Extremely abrasion resistant, recommended for high pressure hydraulic, water and
steam service.
At high speeds and with soft metal surfaces may be abrasive wear possible.
PTFE-reinforced with special filler	-155...+316°C
Superior wear and heat resistance. May also be used for soft metals. No abrasive wear.
Recommended for static and dynamic service, high temperatures and high speeds.
UHMW-PE modified	-240...+104°C
Excellent wear resistant, but limited chemical and heat resistance. Especially suitable
for abrasive media and water based liquids. FDA approved.
