Dynaflon seals
Vanéflon has been producing this unique Dynaflon seal for more than 30 years.
The Dynaflon® O-ring, Kamlock-, and milkring bring our customers advantages over FEP- or PFA-encapsulated seals.
They combine the chemical resistance of PTFE together with the sealing performance of Viton.
Customers (pharmaceutical, food and chemical industries) who have issues with the life-time of their FEP/PFA-encapsulated seals will find a clear interest and value in using Dynaflon® seals.
PTFE steel lined gasket
PTFE stainless steel lined gaskets consist of a perforated stainless steel insert uniformly enclosed by PTFE. The synergy between the highly corrosion-resistant PTFE mantle and the perfectly centred rigid stainless steel insert give the gasket exceptional chemical and mechanical properties, preventing cold flow in a wide pressure-temperature range. In extreme applications they are highly recommended for use instead of normal PTFE envelope gaskets.
These are standard off-the-shelf gaskets available to DIN 2690 and ASA B.1621.
PTFE envelope
PTFE envelope gaskets are mainly used as flange gaskets in mild to heavily corrosive environments. Since PTFE is an inert material, it is also suitable for direct food-contact (FDA-EU approval).
Vanéflon supplies standard PTFE envelopes or customises them to your specifications. Different types are available.
We have standard off-the-shelf PTFE envelopes available for 2mm inserts according to DIN 2690 and ASA B.1621.
Other Sealing Solutions
Vanétex e-PTFE tape
Our Vanétex tape is made of 100% pure, expanded virgin PTFE material.
Because of the excellent thermal and chemical resistance, it can be used in a wide variety of static applications in nearly all kinds of industry. The exceptional malleability of expanded PTFE can compensate for out-of-parallel and/or damaged sealing surfaces and allows use with stress-sensitive connections and applications where only a limited flange load is available, e.g. plastic flanges, glass flanges, etc. Typical applications are the sealing of flanges, pump housings, compressors, handholes and manholes, compensators, heat exchangers and many more.
Thread Seal Tape
PTFE tape is thin-film tape used by heating engineers and plumbers for sealing pipe threads. The tape can be used in a number of pipework and plumbing applications, including being wrapped around pipe threads and joints to form a tight seal, which helps to stop any leaks. This type of tape is available in different thicknesses and sizes.
Special gas-approved tapes are also available.
Packing cord
Our packing cord is a firm, pliable interlock braided packing manufactured from the purest ePTFE filaments. A proprietary food-grade lubricant provides faster break-in and reduced shaft wear. It is food compliant according to FDA and EU regulations.
It resists most caustic media and is commonly used in centrifugal and rotary food processing equipment. It is also used in blenders, mixers, cookers, dryers and pumps.
Spring-energised seals
A spring-energised seal consists of a spring and a high-performance plastic sealing jacket. It uses the spring to provide a consistent load throughout the circumference of the seal. This way a leak-tight seal is created between the jacket, made out of a high-performance plastic, and the hardware. The choice of high-performance plastic provides outstanding physical and mechanical characteristics.
Spring-energised seals are typically used in environments that place too much strain on conventional elastomeric seals: extreme temperatures and pressures, high levels of friction and wear or aggressive media are among the most common.
