Garter Spring Overview
Handa’s Oil Seal Springs are purpose-designed metallic springs used to energize oil seals in demanding environments. By maintaining optimal lip pressure against shafts or housings, they prevent oil leakage—even at high speeds, under heavy loads, and across wide temperature ranges. Ideal for industrial machinery, automotive systems, marine applications, and power generation equipment, these springs ensure reliability in mission-critical applications.Elgiloy®, Stainless Steel, ensuring excellent corrosion resistance, fatigue life, and sealing reliability in demanding environments.

Custom Manufactured
Cusom Garter Springs
At Handa Spring, we specialize in custom oil seal springs (garter springs) engineered to deliver precise sealing performance. Every spring is manufactured to meet your exact design—diameter, wire size, spring force, and material selection are fully customizable.
Whether you need standard stainless steel (301/302/316), or advanced alloys like Inconel® or Elgiloy®, our team ensures durability in demanding environments such as automotive, pumps, compressors, and industrial machinery.
We provide fast prototyping, free samples, and no minimum order quantity, helping you achieve leak-tight sealing solutions with reduced lead time. Partner with us for springs tailored to your oil seal designs—reliable, precise, and built to perform.
Several Ways To Connect the ends
The manufacturing process is not much different from the creation of regular coiled springs, with the addition of joining the ends together.
This can be accomplished through a few different ways:
- Laser-Welded End: Laser-welded oil seal springs deliver strong joints, enhanced durability, and precise sealing performance, ensuring reliability and long service life in demanding industrial applications.
- Tapered End: Reducing the diameter on one end of the spring so that it fits into the other end (nib joint). This is the most common method used. It is crucial to back-wind the spring to prevent twisting tension that could deform the spring.
- Connected End: Interlocking the loops at both ends of the spring through a smaller springs or rod.
