Spring Energized Seal Manufacturer

Hansealing specializes in the manufacturing of spring energized seals for demanding industrial sealing applications.

Our key advantage is vertical integration: we manufacture the spring energizer inside the seal in-house.

This gives us greater control over spring geometry, spring force, materials, customization, production scheduling, and lead time.

From standard sealing configurations to custom designs, we combine polymer sealing materials with application-specific spring energizers to produce complete sealing solutions.

MANUFACTURING ADVANTAGE

We Manufacture the Spring Inside the Seal

The spring energizer is not an accessory. It is a critical component that maintains the sealing jacket's contact force.

Hansealing manufactures spring energizers in-house and integrates them into complete spring energized sealing systems.

This gives us direct control over spring geometry, spring force, material selection, heat treatment, finishing, and production scheduling.

What Our Customers Are Saying

HanSeal Tech’s cantilever spring seals transformed our hydraulic cylinder operations. We’d struggled with rubber u-cups failing in high-temperature environments, but their PTFE-based seals have lasted 3x longer—no leaks, no downtime. The team even customized a size for our older equipment. Game-changer.

Mark T., Plant Manager, Industrial Hydraulics Inc.

In aerospace, reliability is non-negotiable. HanSeal’s spring energized seals handle our extreme pressure cycles flawlessly. We tested 3 suppliers; theirs had the tightest tolerances and consistent performance. Plus, their rapid quoting on custom designs kept our project on track.

Sarah L., Procurement Lead, AeroComposites LLC

We needed FDA-compliant seals for our food processing pumps. HanSeal’s silicone-filled options met every standard, and their technical team walked us through material certifications. Shipped in 48 hours—impressive service for a niche requirement.

Raj K., Operations Director, FreshFlow Processing

Oil & gas applications are brutal on seals, but HanSeal’s wave spring designs hold up in corrosive mud systems. We’ve cut replacement costs by 40% since switching. Their responsive support when we needed urgent replacements? Priceless.
