Bal Seal Engineering Products

Proven

Trusted by engineers and OEMs to protect critical equipment used everywhere, from deep sea to deep space.

Versatile

Delivers superior rotary, reciprocating, oscillating, static, and face sealing performance. Sizes range from 0.020 in. to 120 in. ID.

Bal Seal® spring-energized seal

High-performance

Promotes even jacket wear and resists breakdown to extend service life by up to 150% over standard seals.

Predictable

Combines custom polymers, backup elements, and locking rings 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.

Bal Spring® canted coil spring

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

 Ensures multi-point electrical contact and redundant power/signal paths. Compensates for tolerance variations, and exhibits extremely low contact resistance.

Compact

Employs springs from 0.5mm (.020 in) and housings with pitch of ~2mm.  Supports smaller, more functional devices.

Medical Contact

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.
