- Commodity name: Spring Energized Oil Seal
- Commodity ID: PC-0092
Spring energized oil seals are essentially lip seals, or U-cups, comprised of high-performance elastomers—typically polytetrafluoroethylene (PTFE). This highly-durable polymeric jacket is reinforced with a corrosion-resistant metal spring energizer that supplies a constant load to the lips, creating a reliable gas-tight barrier against all contacting sealing interfaces.Spring-energized seals are subsequently an effective combination of elastomeric and metallic sealing concepts.
Jackets:
Although a choice of fluoroplastic compounds and engineered plastics can be used for spring jackets, PTFE is widely considered the gold-standard owing to its exceptional durability and high tolerance to extrusion.
Virgin polyetheretherketone (PEEK) is sometimes recommended for back-up rings and high-temperature applications,
while formulated ultra-high-molecular-weight polyethylene (UHMW-PE) is valuable for dynamic sealing applications with high wearing forces.
Energizers
Spring energizers vary depending on the chemical properties of the fluid media they are likely to encounter.
Stainless steels offer good all-around performance with near-universal chemical resistance, but diagnosing the right grade for the job will have a direct impact on the lifespan of the spring-energized seal.
Type 301 stainless is among the most common alloys for spring energizers。
At the heart of almost every rotary seal is an energizer that’s precision-engineered to promote even wear and longer seal service life.
Choosing the right energizer—with the ideal combination of force, fit, and finish—is as critical to the success of your design as the seal material itself.
