Garter spring Manufacturers

European Springs & Pressings is a top UK garter spring manufacturer. We have decades of experience in spring design and production. As part of Lesjöfors, we supply standard stock options and custom garter springs for many industries. All our processes meet strict ISO 9001 quality standards. This certification guarantees that every spring we produce is safe, reliable, and built to last. 

We manufacture heavy-duty springs for oil seals and precise parts for electrical connectors. Our team builds high-performance solutions tailored to your exact needs. Contact our technical team today. We can discuss custom sizes, wire diameters, and force requirements.

What Is a Garter Spring and How Does It Work?

A garter spring is a coiled steel spring. It connects at both ends to form a continuous ring. We make them as compression springs or tension springs. Extension types are the most common choice. In extension setups, the spring exerts a clear radial force inward toward the centre.

This radial force keeps continuous contact around circular objects. These include shafts, lip seals, and piston rings. A garter spring copes well with changes in heat, pressure, and wear. As heat causes materials to expand or shrink, the spring adjusts instantly. The radial force must stay stable over millions of cycles. Because of this, exact coil pitch and wire quality are vital. They protect key machinery from fluid leaks and contamination. By keeping a tight seal, these springs prevent costly damage to surrounding mechanical parts.

Custom Garter Springs & Material Options

We offer full custom options for bespoke garter spring manufacturing. Our engineers work with you from early design ideas to final production. We carefully select materials based on working conditions, operating temperatures, mechanical loads, and exposure to corrosive agents.

Our primary material options include:

  • Carbon Steel: High strength and durability at a great price. It is ideal for general industrial uses with low moisture exposure. This material is easy to form and retains its shape well. 
  • Stainless Steel: Great resistance to rust, moisture, and chemical exposure. Ideal for marine, medical, food processing, and outdoor uses. It offers a very long lifespan in damp or wet conditions. 
  • Special Alloy Types (Inconel, Phosphor Bronze, Hastelloy): Made for extreme heat and harsh chemicals. Used in aerospace, subsea, and power units. 
  • Plated Spring Steels: Protective coatings add defense against wear and rust in tough environments.

Connection Types for Bespoke Garter Springs

The joint method connects the spring ends. It is vital for performance and easy fitting. Our CNC winding machines create precise joints for tight spaces:

  • Hook & Link Joint: This setup uses a hook on one end and a loop on the other. You can assemble and take it apart by hand. This makes it ideal for parts that need quick checks or frequent replacement. Engineers often prefer this style for fast on-site machinery repairs. 
  • Nib Joint: This is also called a screwed-end joint. We reduce the outer diameter on one end of the spring. This nib end screws tight into the open coils of the other end. It forms a smooth, continuous loop with no outer loops. This joint works best in small spaces and fast rotating seal setups. The secure fit stops the spring from coming apart under high speeds.

Industrial Applications Across Key Sectors

Garter springs are vital parts in demanding fields. As leading UK garter spring manufacturers, we supply custom solutions for key sectors:

  • Automotive Sector: Radial oil seals, engine transmission components, and fuel pump assemblies
  • Oil, Gas & Petrochemical: High-pressure valve packing, subsea wellhead seals, and fluid pipes
  • Heavy Machinery: Hydraulic pump seals, drive shafts, and motor protection. These springs handle heavy vibrations on a daily basis
  • Aerospace: Sealing units for engines and flight control systems
  • Electrical: Conductive circular connectors and high-voltage shield rings
  • Medical Equipment: Sealed pump units and diagnostic tools requiring constant spring tension

 

European Springs & Pressings uses modern CNC coiling tools. We make garter springs with consistent radial tension and tight limits. We handle small prototype orders and large production runs with ease. Our factory can scale up output quickly to meet urgent client deadlines. 

We also offer complete extra services to support your manufacturing process:

  • Prototyping & Load Testing: In-house force measurement and stress analysis to verify performance before full production.
  • Surface Finishing & Coatings: We fit springs to mating parts to speed up your assembly line. 
  • Sub-Assembly & Packaging: Assembling springs with mating components to simplify your production line.
  • Technical Guidance: Our engineering team helps you pick the right spring type, material, and wire size.

 

Along with garter springs, we manufacture compression springs, extension springs, torsion springs, and custom metal pressings. Our expert team gives full support from initial design to final delivery. Request a quote today to discuss your project specifications.

Frequently asked questions

What Are Garter Springs?

A Garter Spring is a circular ring made from a coiled helical spring bent into a circle with the two ends connected to each other, creating a loop. This provides a strong radial force which is directed towards its centre when its radius increases.

As the spring’s radius expands, it exerts an inward radial force, which keeps the spring securely in place and maintains contact with the surrounding surface. This is particularly important in certain dynamic environments where pressure must remain constant.

  • Machinery & Tools: In belt-driven engines and conveyor systems they help keep everything in place, ensuring parts move as they should without falling out of alignment.
  • Oil & Gas: In oil seals and shaft seals, their steady radial force holds seals securely and preventing leaks whilst helping it last longer in applications such as car engines or heavy industrial equipment.
  • Electronics: Garter springs are often found in electrical connectors to facilitate a reliable and secure connection, maintaining consistent contact pressure.
  • Medical: Several advanced medical devices use garter springs, like catheters and stents.
