Exactly the Right Product

It doesn’t always have to be a specification. For developers and especially for buyers, it’s worth taking a look at the extensive range of Angst+Pfister on www.angst-pfister.com - or a visit to the online shop www.apsoparts.com.

Whether it is an O-ring or hose, a cone bearing for vibration isolation, visually recognisable plastics or a toothed belt: The Angst+Pfister range includes more than 100,000 standard products.

They can be ordered online and are available immediately for the most part. Standard products and individual advice are not mutually exclusive.

The international engineering team, which designs sophisticated solutions for its customers, provides support as needed.  On the one hand, a large number of the standard products have emerged directly from successfully tested engineering solutions from Angst+Pfister, so that today the customer pays well for the product, but not for its design. And on the other hand, the experts from Angst+Pfister also use standard products for their customised designs, which they specify further. The straightforward order process is complemented by lean logistics. It is able to fully integrate into the customer's supply chain, and it can thereby further reduce costs.


APSOseal® HITEC® O-ring

The Angst+Pfister HITEC® O-ring range includes O-rings with approvals for drinking water, food, pharmaceutical and medical technology in the materials NBR, EPDM, VMQ and FKM. The material EPDM 70.10-02 is particularly worthy of note, since this material, in addition to outstanding mechanical properties such as low compression set also has all the approvals in the aforementioned industries - and for a single material too.


APSOseal® FEP-O-SEAL® O-ring

The FEP-O-SEAL® O-ring is the optimal combination of two materials: The core of elastic silicone or FKM ensures the restoring force and the FEP sleeve guarantees the chemical resistance. FEP-O-SEAL® O-rings are ideal for use in the food, pharmaceutical and medical industries: They can be deployed in a variety of applications at temperatures ranging from –60 °C to +200 °C. In addition, they are pressure-resistant and guarantee low compression set coupled with much lower tendency towards cold flow compared to PTFE. They also have FDA and EG1935/2004 compliance, as well as 3A Sanitary Standard and USP Class VI.


APSOseal® Kalrez®
perfluoroelastomers (FFKM) O-ring

Kalrez® O-rings possess unique operational properties that are unmatched by any other elastomer material. Kalrez® synthetic rubber in its various compounds combines the elasticity and sealing power of a genuine elastomer with the chemical resistance of PTFE. Kalrez® O-rings are resistant against practically all chemicals and can be deployed in continuous operation at temperatures up to +327 °C or for brief periods at temperatures up to +350 °C. Kalrez® O-rings compliant with FDA or USP VI requirements are also available. Angst + Pfister stocks a huge assortment of Kalrez® O-rings and has direct access to special-sized Kalrez® O-rings. Where conventional materials fail, Kalrez® perfluoroelastomers (FFKM) provide the least expensive and most reliable long-term solution from a total cost standpoint.


APSOvib® H-Mounts

APSOvib® H-Mounts are specially designed for the secure attachment of devices to mobile applications, can be used on agricultural and construction machinery, trucks and trailers, special vehicles and for all industrial applications:


  • Typical applications include the isolation of motors, gearboxes and differential cases, cabin vehicles, auxiliary equipment such as radiators, radiators, compressors, pumps and generators, attachment of exhaust ducts and exhaust pipes in the industry.

  • 3 different versions cover a load capacity Fz from 405 to 16'000 N.

  • Each item is available from stock in soft, medium soft, medium hard and hard.


APSOvib® conical bearings

APSOvib® conical bearings are designed for use in agricultural and construction machinery to absorb impact and isolate engine vibration in cabs.

  • Typical applications include the isolation of motors, gearboxes, differential cases, cabins, and others.

  • Conical bearings can be used for loads from 2'600 N to 30'000 N.

  • They are available from stock in six different sizes, each in different rigidities and breakaway-proof by the use of stop discs.

  • The directional stiffness allows a good vibration isolation in the vehicle transverse direction and sufficient rigidity in the direction of travel for the suspension of shock and braking forces.

APSOplast® Visually recognisable plastics
according to FDA and EC 1935/2004

These visually recognisable blue plastics stand out clearly from the colour of processed foods and help with the visual inspection of food. Any fragments of a plastic component can be recognised quickly. The optical recognition is economical and has proven to be successful in a variety of applications in the food industry. Our customers have successfully used blue plastics not only in food processing machines but also in pharmaceutical and medical devices.

These plastics are suitable for direct and indirect food contact according to FDA and EC 1935/2004. They are available as POM-C and PE-UHMW in plates and rods.



The BRECOFLEXmove® is a timing belt specifically designed for high performance drives and traction drives with a particularly high stiffness requirement. A newly developed Steel cord tension member increases belt stiffness and tear-resistance, making transmission of stronger forces possible. The tooth flank geometry has been optimised through the Finite Element Method (FEM). This leads to an optimisation of the contact pressure distribution and reduces the work of friction between the timing belts and tooth washer, thus minimising wear. In addition, a friction optimised laminate coating is applied to the tooth side.


APSOfluid® TETRAFLEX® S PTFE hose lines

PTFE (also known as TeflonTM) is one of the most versatile plastics on the market: It has almost universal chemical resistance and withstands temperatures from -60°C to + 260°C. Our TETRAFLEX® S PTFE hose assemblies have an inner tube made of this unique material and are therefore suited to a wide variety of applications. Due to the external braiding made of stainless steel, the pipes also withstand high pressure and have good kink resistance. The pipe connections can be individually adapted to the customer's wishes: Normal closing, custom-made, stainless steel or galvanized steel. The selection of TETRAFLEX® S PTFE pipes is also varied: they are available in diameters DN 5 - DN 25, in antistatic versions or with multi-layer braiding for particularly high pressure resistance.
