Bal Seal Engineering: Custom Seals, Springs & Connectors
Bal Seal Engineering’s three core product lines deliver complete solutions for critical applications. Our spring-energized seals, canted coil springs, and electrical connectors share the same advanced spring technology, providing superior performance across aerospace, medical, and industrial applications.
Proven
Trusted by engineers and OEMs to protect critical equipment used everywhere, from deep sea to deep space.
Versatile
Delivers superior rotary sealing, reciprocating sealing, oscillating, static, and face sealing performance across all applications. Custom seal sizes range from 0.020 in. to 120 in. ID for precision sealing applications.
Custom spring-energized PTFE seals combining advanced polymer materials with canted coil spring technology for superior sealing performance.
High-performance
Promotes even jacket wear and resists breakdown to extend seal service life by up to 150% over standard sealing solutions.
Predictable
Combines custom PTFE polymers, backup elements, and locking rings with wear-regulating spring energizers to resist extrusion and provide more uptime, less maintenance.
Adaptable
Compensates for large tolerances and surface irregularities, ensuring multi-point electrical contact for improved reliability, longer equipment life.
Precise
Enables accurate control of insertion and removal forces, from just a few ounces to 1000s of pounds.
Canted coil springs providing consistent force for sealing and mechanical connecting applications, efficiently managing electrical current in conducting applications, and protecting sensitive electronics from the harmful effects of electromagnetic interference, or EMI. Performing across wide temperature ranges.
Multi-functional
Mechanically connects, conducts current, grounds, and shields against EMI/RFI. Simplifies designs, reduces weight, and even dissipates heat.
Robust
Maintains consistent insertion and removal forces over 1000s of cycles. Resists compression set better than fingerstock, mesh.
Ultra-Reliable
Canted coil spring technology ensures multi-point electrical connectivity and redundant power/signal paths. Compensates for tolerance variations and exhibits extremely low contact resistance throughout operational life.
Compact
Employs springs from 0.5mm (.020 in) and housings with pitch of ~2mm. Supports smaller, more functional devices.
Spring-loaded electrical connectors that employ canted coil spring technology for reliable multi-point connectivity in demanding environments.
Proven
Used in millions of medical implantable devices worldwide, it’s the designer’s choice for applications that simply cannot fail.
Flexible
Can be supplied with pre-tested seals, creating a turnkey system that eliminates sourcing and speeds product development.

Why Engineers Choose Bal Seal Technology
Every component we make is begins and ends its journey in certified facilities with comprehensive quality control, ensuring consistent fit, finish, and performance. Whether you need 10 prototypes or 1 million production units, you can be confident that every seal, spring, or contact meets your strict requirements – and ours.
150% longer service life compared to standard sealing solutions.
Zero leakage performance maintained throughout operational life.
Consistent force and contact pressure as materials naturally wear.
Multi-point electrical reliability compensating for tolerance variations.
Reduced downtime with fewer, more predictable maintenance intervals.
We deliver our custom seal, spring, or contact proposals in as little as 3 working days, and functional prototypes in 4-6 weeks. With our combination of engineering and manufacturing expertise, we help you accelerate your development cycle and avoid costly design pitfalls.
Our seals, springs, and contacts don’t just solve engineering challenges; they help you achieve performance breakthroughs and gain a competitive edge. By making your designs smaller, lighter, faster, less complex or more robust, our products enable you to focus on technical advancement and meet evolving user demands.
From Apollo lunar missions to the Mars Perseverance Rover and Ingenuity copter, our seals, springs, and electrical contacts/connectors have performed flawlessly in the harshest environments imaginable. This same proven technology protects millions of medical devices and critical defense systems that simply cannot fail.
When you work with us, you get more than a spring, seal, or contact. You get access to worldwide technical support and a vast application knowledge base built on nearly 70 years of problem-solving for medical, aerospace, energy, industrial, and many other industries.
