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.
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.
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.
