Better known under the brand name Variseal®, Spring-Seals are seals machined in a U-shape, into which a V-shape spring is inserted to maintain the pressure of the lips against the surfaces to be sealed.
For Dairyfood applications, it is recommended to fill the seal groove with FDA or 3-A Sanitary approved silicone to prevent product remaining in the seal’s central cavity and bacteria developing.
Since its inception, PICARD Technologies® has been offering various types of bellows to help clients protect their machines.
Do the bellows need designing for a first assembly or is the design based on existing specifications? Are they to be mounted on an older or on a new machine? Whatever or wherever the application, we will help you choose the right solution.
Below, are the most standard shapes and our range of materials.
The great classic, offering excellent value for money:
Flexible and hard-wearing black or translucent FDA-approved PVC, for use in environments with no risk of abrasion, cuts and nicks. Good resistance to oil and greases. Service temperature range of -15°C to + 65°C. Available with zips or Velcro®.
Fabric bellows :
Designed to cope with substantial mechanical strain, fabric bellows provide a high level of protection against tears and abrasion and are suitable for high temperature applications. The optimal fabric for the operating conditions is selected, then cut to size and stitched.
We also construct bellows from materials such as Kevlar®, Nomex® and polyester, depending on the duties the bellows are to perform.
These materials offer exceptional resistance to friction and abrasion and serve in higher temperatures than PVC. Also available silicone-coated or aluminized.
Most of our products can be fitted with snap fasteners, zips or Velcro® to avoid having to dismantle the equipment that needs protecting.
Certain applications require stiffeners, guide frames, rollers or wearing pads.
Bellows out of PTFE (Teflon®) can also be machined to measure.
For more stringent applications, we recommend the bellows be molded out of an elastomer specifically selected for the purpose.
We can create a mold and mold your parts at our facilities, and even personalize each part by engraving your logo, brand name or reference codes in the mold. The parts can also be colored to your specifications.
PICARD Technologies® has been helping valve manufacturers improve the sealing integrity of their products for over 30 years.

Our Sideseal® line includes an array of profiles. Ask our specialists to recommend the right ones for your application requirements. Browse the Sideseal® catalogue...
The Sideflon® option might be recommended for certain applications. Sideflon® is a Teflon® PTFE-filled coating, molded over the lip of the Sideseal®. The Sideflon® option:
- reduces the temperature caused by the friction of the Sideseal® on the rotating shaft;
- reduces the coefficient of friction;
- increases the Sideseal®’s working life;
- allows for higher rotary speed.
|The Sideflon® option is ideal for duties requiring large-diameter shafts.|
Sideseals® can be cut to the customer’s required length for easier assembly or when required by the installation. In such cases, the Sideseal® is molded with an all-elastomer section where the cut will be made. Once fitted in its housing, the two ends of the all-elastomer section ensure a tight seal.
What is Sideflon®?
Sideflon® is a modern material developed by PICARD Technologies® in 2011.
The original objective was to obtain a material whose technical properties would rival, if not better, those of PTFE + 25% carbon/graphite, a benchmark in the industrial sector, while remaining food grade (FDA and EU 1935/2004).
After 3 years of trials and multiple tests, we exceeded our ambitions.
Sideflon’s® main properties:
- Low coefficient of friction (0.19 versus 0.34 for PEEK-filled PTFE or 0.6 for bronze-filled PTFE);
- Good PV limit, ideal for slide bearings;
- Low thermal expansion coefficient compared to PTFE;
- Excellent chemical inertness: resistant to oil, greases, vapors, solvents, hydrocarbons, etc...;
- Resistant to hydrolysis and low moisture absorption < 0.02 %;
- Food safe (FDA-approved, EU 1935/2004, 3-A registration in progress);
- Good resistance to cleaning agents used in the food industry (CIP);
- Temperature range of -180° C to +260° C, depending on end application;
- Excellent wear rate (5.2 compared to 7 for 25% carbon/graphite PTFE);
- Eliminates stick-slip effect, ideal for applications requiring very precise, smooth movements;
- Ideal for piston seals, composite seals or volumetric filler pistons.
Our tests show that, in certain applications, Sideflon® lasts 4 times longer than certain filled PTFEs, such as 10% Ekonol® PTFE or 10% PEEK PTFE.
Sideflon® is a registered trademark of PICARD Etanchéité®.
We carry an extensive selection of metering and inch pistons in our standard range, spanning 14 mm to over 200 mm in diameter, all made entirely in our on-site workshops.
We study and design the perfect piston solution, be it for the modification, improvement or renovation of existing machines or simply for the replacement of an existing model. We rigorously select the optimal materials for your piston, based on the part’s employment and its cleaning parameters.
Volumetric fillers are normally filled via conical shut-off valves or rotating disc valves.
These shut-off valves or rotating disc valves are made from several materials, carefully selected for their properties that help optimize the functioning of the machines.
As with the pistons, we study and design all the parts in our workshops.
One of our slogans is “Control” so, back in 1995 when we were starting production of elastomer parts and molded seals, we made the decision to make our own molding tools, at PICARD Technologies®.

PTFE, or polytetrafluorethylene, is a material that looks like plastic. It is naturally white and translucent and is similar in hardness to a natural polyethylene.
The main properties of PTFE
(Teflon®, trademark of Dupont de Nemours®):
- Very low coefficient of friction
- Resists most chemicals
- Good electrical insulation
- Good water repellency
- Low resistance to abrasion
- Low PV limit (weight applied to a given surface x velocity)
- High coefficient of thermal linear expansion (virgin material)
- Poor notched impact resistance
- Poor compression set resistance (poor DRC)
Fillers can be added to enhance PTFE properties. The PTFE is then said to be reinforced. Some of the filled PTFEs most commonly used in various industries include:
- Glass fiber-filled PTFE (5, 15, 25%)
- Carbon fiber-filled PTFE and carbon fiber + graphite-filled PTFE
- 15% Glass fiber and 3% MoS2-filled PTFE
- Bronze and/or bronze + MoS2 or graphite (40%, 55% + 3% MoS2, 60%)-filled PTFE
- Polyimide-filled PTFE
- Ekonol®-filled PTFE
- Graphite-filled PTFE
- Other special fillers
- SIDEFLON® (Click here for technical data sheet.)
Before being processed, natural or virgin PTFE (Teflon®) is a white, fairly fine powder. The powder is extruded or compressed at very high pressure in a mold cavity to obtain a finished part or a semi-finished product, such as a block, plate, tube or a bar. Semi-finished products are then machined to obtain finished parts.
PTFE (Teflon®) is also used as an anti-friction agent in oils and lubricants or as a non-stick coating for cooking pans, pots and utensils.
PTFE’s water repellency means that it is also frequently used in the manufacture of clothing.
Certain grades of filled or unfilled PTFE have applications in the agri-food industry and the medical field.
At its Valenciennes site, PICARD Technologies® produces various grades of unfilled and filled PTFE that meet FDA, 3A Dairy Sanitary and USP class VI requirements.
We can make semi-finished products (rods, tubes, plates and sheets) out of virgin or custom-filled PTFE. We can also machine your parts.
If you need high quality material in PTFE and filled PTFE, please request our technical department.
