iConnFlex™ Canted coil springs are sold in welded spring rings or in cut length. The wire diameters range from 0.1 mm (0.004 inches) to 1.80 mm (0.071 inches). Material choices vary from stainless steel, copper alloys, nickel alloys, to titanium. Surface plating is optional.

Springs that fit ALL of the following criteria are standard:
1) Wire diameter between 0.25 mm/0.010 inches and 1.50 mm/0.059 inch
2) Coil width larger than 1.8 mm/0.071 inches and unwelded length below 150 mm/5.9 inches

3) Stainless steel or copper alloy wires
4) Light or medium in spring force

Non-standard springs are also available at higher prices. Please contact us directly for a price quote at quote@iconneng.com or sales@iconneng.com. 

Different configurations of canted coil springs can provide different connecting forces.

Figure 1: Radial Spring Application

​ A connector with a radial iConnFlex™ canted coil spring provides a specific sliding force and electric current capacity. A circular spring can also fit into a rectangular groove.

Figure 3: Swap canted coil springs to achieve different connecting force or electric current capacities

The canted coil springs in the image above are the same in size - all can fit into the same spring groove. However, the differences in spring configurations result in significantly different connecting forces or electric current capacities. Each iConnFlex™ canted coil spring essentially creates a functionally different connector without changing the connector's dimensions or appearance.

Figure 2: Axial Spring Application

​ An axial iConnFlex™ canted coil spring can compensate for the surface unevenness and maintain a constant surface contact in a knife connector. Axial springs can also be used in pressure relief valves.

Canted coil springs can be sold in length or as spring rings
iConn Engineering's canted coil spring production is ISO 9001 certified (SGS Certificate ID TW20/10209)
iConn Engineering uses only DFARS compliant materials for all canted coil springs.

Canted coil spring


iConn Engineering's canted coil springs are ITAR compliant.

Canted coil springs, sometimes called slant coil or slanted coil springs, are ideal for push-pull and snap-on connectors (Figure 1), or pressure relief valves (Figure 2). They allow engineers to customize connector space, target connecting and disconnecting force, while maximizing the spring's high electric current capacities. In a latching application, the connector's insertion and removal force can differ by 10 folds. The simplicity of a canted-coil-spring-enabled application also translates into minimal assembly time, fewer material consumptions, less complicated systems, and lower overall costs.​​
