Canted Coil Springs
Canted coil springs, also known as wire wound springs, slant springs, or seal springs, have many advantages. Canted coil springs create continuous predictable loads within a very wide deflection range. These are generally produced using Stainless Steel 302 or 316; however, other alloys are available upon request. Nearly Zero Compression Set. We offer a full range of cross-sections 000-400 for Light, Medium & High Load Applications.
Our canted coil springs are cut to length and laser welded to your specifications or in a standard continuous length. Standard lead time on Stainless standard cross-sections is less than 3 weeks and 6-8 weeks on all other alloys.
MANUFACTURED SPRINGS
Looking for Pre-Cut and Welded Radial Springs?
MW produces cut and welded springs for all standard industrial and metric dash sizes for 000 - 400 series spring energizers, including V-spring, Helical, and slant coil springs. Simply provide the dash number you need and we'll cut and weld the spring to the necessary dimensions.
Even if the product you need doesn't fall into the standard dash number range, we still have you covered. Provide the centerline of the spring groove in the seal and we will cut and weld a spring energizer to exactly match the dimensions. Our engineering and manufacturing experts are here to make fabrication and assembly as seamless as possible.
Canted Coil Spring Dimensional Data
The chart below shows the standard dimensions for our canted coil springs. All dimensions are subject to standard manufacturing tolerances. Those tolerances may be requested if needed. Each canted coil spring is manufactured in its own standard tool & die set.

Canted Coil Springs in Medical Applications
Canted coil springs, or slant coil springs are extensively used in the medical industry for their precise, repeatable force and ability to provide reliable connections in critical applications – specifically quick connect/disconnect. With customizable load and deflection characterized, canted coil springs can provide fast, secure connections in critical applications such as surgical instruments and diagnostic equipment.
Canted coil springs are also commonly used as electrical connectors and spring energized seals. As electrical connectors, canted coil springs help provide secure, low-resistance connections in implantable devices like pacemakers and neurostimulators, where consistent performance is essential. When used as a sealing tool, canted coil springs are paired with a polymer jacket, often made from biocompatible materials like PTFE or UHMWPE, and are used in medical devices such as infusion pumps, ventilators, surgical instruments, and diagnostic equipment, where precision and cleanliness are paramount. In these applications, spring-energized seals guard against leaks under changing conditions, such as repeated movements or pressure fluctuations, while withstanding exposure to sterilization processes, chemicals, and biofluids.
In addition to mechanical locking or holding applications, connecting for optimum electrical conductivity is possible due to the small coil size and the number of independent coils. In regard to EMI/RFI shielding applications, the canted or slant coil spring offers an economical design option that can reduce radiated and conducted interference to prevent premature failure in electrical devices. Electromagnetic and radio frequency interference can be very dangerous for medical equipment, having the potential to disrupt its normal operation or comprise the integrity of data transmitted or received. For this reason, you will often find canted coil springs in electrical enclosures or used with data transmission cables. These springs can be customized and tuned to meet impedance specifications to protect equipment from crosstalk interference.
Canted Coil Springs in Oil & Gas Applications
Canted coil springs are frequently used as spring energized seals to ensure leak-proof performance in extreme environments such as those found in the oil & gas industries. In sealing applications, canted coil springs are combined with a durable polymer jacket, often made from materials like PTFE, to provide exceptional resistance to high pressures, extreme temperatures, and corrosive chemicals.
Commonly used in valves, pumps, compressors, and downhole tools, canted coil springs help maintain a tight seal even under dynamic conditions, such as rotational or reciprocating motion. The spring ensures continuous contact between the seal and the mating surface, compensating for wear, pressure fluctuations, and misalignments. By preventing leaks and maintaining system integrity, spring-energized seals enhance the safety, efficiency, and longevity of critical oil and gas equipment.
