Production of seals, bushing & sliding and machined parts

Techne's know how

Sealing

Rubber seals

Depending on the shape and application of the seals, they are made of injection or compression, some are dipped.

O-Rings-Products-Techne

O-Rings: Available on stock from ID 0,4 mm to ID over 2000 mm, we dispatch each year more than 3 000 000 O-Rings across all models.

We have more than 10 000 references on stock, a hundred feasible mixtures according your requested applications and approvals.

Our range material is wide: NBR, FPM, MVQ, CR, ACM, FFKM, FMVQ, HNBR…

O-Rings can also be machined in the most popular materials: PTFE, Polyurethane, NBR, FKM…

We provide materials with appropriate agreements: FDA, 1934-2004, ACS, KTW, EN 549, USP VI… Others approvals are available according your demand. We manufacture also machined parts in PTFE, POM, PA and Polyurethane.

On request we can also provide O-Rings according to food (FDA, 1935/2004), gas, drinking water and medical approvals.

For aggressive environment such as use in contact with chemicals and perfumes, we can offer encapsulated O-rings (FEP and PFA)

Our O-Rings are also available as O-Rings boxes. We provide you too rope rolls in NBR, EPDM, FKM, MVQ red or translucent.

Rotary-Seals-Products-Techne

Rotary seals: We provide more than 7000 references on stock. We can realize rotary machined seals for prototype or small series in elastomer or in PTFE.

We have also on stock mounting tracks for rotary seals.

Rotary seal is one of our speciality and today we can propose you more than 50 different profiles.

  • Single or double lips
  • Pressure resistant oil seal DL-HP
  • PTFE lip steel cage for high temperature, high speed and high pressure.

We provide also End Cap (TVK), Axial face seals (RB) and Speedy Sleeve.

V-Seals-Products-Techne

V-Seals: V-seals are secondary seals that work axially. They protect the mechanism from dirt or dust. Very low friction because of the little contact section.

We provide 4 different designs:

  • Type VA (the standard)
  • Type VS (bulkier than the VA, advised for small dimensions)
  • Type VL
  • Type VE (advised for big dimensions)

Our V-seals have a shaft from Ø 2.7 to Ø 2020.

In order to fall the friction coefficient or to provide mounting assistance for our V-seals, it’s possible to apply a high performance surface treatment developed by us.

JT4-Products-Techne

JT4 : It’s a four lobed double acting seal. Thanks to its symmetrical shape, it is energized by the pressure which increases the quality of the sealing. The shape of the JT4 is similar to 4 tangent O-Rings.

JT4 are also called Quad’rings or X’rings. They are available in NBR or FKM. In order to facilitate the sliding, our standard NBR includes a slip agent.

We can propose you other materials according to your need.

Do not hesitate to contact us for JT4 in FFKM or EPDM.

JR-Products-Techne

JR Fitting seals: Techne JR fitting seals are used in male threaded connexions in hydraulic applications. Its simple shape allows a quick and easy mounting.

JR fitting seals are available in NBR, FKM and EPDM.

On request, we can produce also in FFKM.

Its dimensions are in accordance with the DIN 3869.

JR fitting seals in NBR are black and FKM ones are green.

Aseptic-Seals-Products-Techne

Aseptic seals: They are widely used in food-processing, pharmaceutical and wine-producing industries.

We provide 3 different family profiles:

  • Clamp, clamp micro, clamp mini and PTFE enveloped clamp seal.
  • D-Ring milk coupling seals, standard or flanged
  • SMS seals, standard or flanged

Our profiles are available in NBR, FKM, EPDM Peroxide, MVQ, FKM and PTFE according to the standards SMS, DIN, ISO and USOD.

We can also produce special dimensions according to your application.

We have a wide range of approvals: FDA, ACS, KTW, WRAS, USP Class VI, 3 A, 1935/2004.

We machine PTFE enveloped clamp seal.

Surface treatment

T-Surf-Surface-Treatement


T-Surf® : Techne T-Surf treatment guarantees seals free from any contaminating substances which could damage paint or electric instruments.

They meet the cleanliness and non-contamination requirements of the electronic and automotive industry.

The original properties of the material- mechanical properties, alimentary and certifications- are preserved.


T-Color-Surface-Treatement


T-Color® : A coloured coating is applied on the part. Before doing so, the surface of the part is activated to ensure a better binding. This coating allows a better identification of the seals while maintaining the original properties of the elastomer.

This coating also improves the friction properties of the parts. The colour resists to dynamic and mechanical stress. Techne works with RAL and PANTONE colour charts. Try it!


T-Lub-Surface-Treatement



T-Lub® : This surface treatment eases the mounting of the parts for a small additional cost.

The deposited lubrification agents are not physically linked with the material itself. After time, the treatment is less efficient. For all dynamic applications chose a T-coat solution.


T-Coat-Surface-Treatement



T-Coat® : It is a half-permanent or permanent lubrification coating. These coating are able to meet simple mounting requirements or high stress dynamic applications. The parts will keep all their initial properties but with a lower friction coefficient and a better wear resistance. The stick-slip effect no longer occurs.

As for the T-Surf surface treatment, the T-Coat meets non-contamination regulations required in the automotive and electronic industry.
