Spliced & Extruded Products

Spliced O-rings are a viable solution when standard O-Rings cannot be used. They are made from extruded cord and then vulcanized to form the O-Ring size required.

Rubber can be extruded into long continuous lengths such as tubing, cord, or custom shapes. Extruded seals are beneficial where long lengths of seals are required or where the same profile is required in different lengths, for instance window and door seals.

Custom-Made to Size for Your Application Requirements

Setting the standard.  Being the benchmark. These are two descriptive statements about our spliced O-ring operation that speak to working harder and finding a better way. We’ve reached new heights for a couple reasons – our extensive inventory of extruded cord stock and state-of-the-art splicing operations far exceed the magnifying glass of quality control. And our commitment to service gives us the edge because we can make and ship orders in as little as 24 hours.

We have a wide range of extruded profiles and sizes available to cut to length and hot vulcanize to size custom extruded products of any diameter.

Materials Expertise

It’s all about the cord stock.  The mechanical characteristics and dimensional accuracy of the cord stock are paramount in achieving a high-quality vulcanization.  We leverage our long history and extensive expertise in O-Ring splicing and extrusion to formulate specific cord stock compounds with low compression set characteristics critical for quality vulcanization and O-Ring integrity.

We utilize a wide range of materials set in virtually every shape and size, including square and X-rings stock.  Adhesives are specially formulated to ensure bond integrity.  All this gives us the ability to create parts for many applications and operating environments.

Quality Before Quantity

Splicing is performed in a climate-controlled environment through hot vulcanization to achieve the strongest and most consistent bond quality. Presses with full digital temperature and time control, guarantees a reliable and repeatable process.

O-Rings are produced to RMA E1 and S2 tolerances and are 100% visually inspected.

Our expertise in materials and splicing techniques extends our ability to splice soft durometer materials (40-50), hollow cord stock, custom shapes, and offer cold bonding when the situation calls for it.

The vast majority of o-rings that DICHTOMATIK offers are manufactured in facilities that are ISO-9001 certified.

Advantages

  • Produce custom O-ring size with no tooling required
  • Elimination of flash at the spliced joint prevents leakage

Capabilities

  • Batch and cure date traceability.
  • Inch and metric cord stock options available from inventory to support quick delivery
  • Common O-Ring Profiles
    -Round – X-Ring(Q)                 -Square(SQ)
  • Cross-sections available range from 0.070 to 1.0 inches and 1.0 mm to 25.0 mm
  • Custom Extruded Shapes
  • Profile, size and material variety
    • Silicone -FKM

    • Fluorosilicone
    • NBR
    • Aflas
    • Neoprene

Dichtomatik uses many attributes to create the spliced ring you need.   We have listed these below as a guide to help you understand and determine what information is required to produce your O-ring to size.

First 5 characters = ID of the part (3 decimal places).
Unless ID>100.000, then 6 characters are used for ID, and all other characters move to the right 1 position and the last character (relaxed/non-relaxed) is dropped. Any ID over 100.000 is assumed to always be relaxed.

Max ID 999.999.
