Krimpa-Seal connectors from NSPA have a tinted, translucent tube that makes them easy to identify by size, yet clear enough that you can ensure the wire is well-seated before crimping.

These heat sealed terminals not only seal out moisture, but create a glued connection that helps retain the wire in the connector.

NSPA has been making sealed crimp connectors in the USA since 1982. If you’re working hard to build an efficient and reliable system, you’ll want to use good hardware down to the terminals.

Butted vs. Brazed

Butted Seam Connectors

Formed when metal is stamped, rolled, and butted to create the connector barrel. Should only be used with stranded wire and must be crimped in the proper place to avoid opening the seam.

Brazed Seam Connectors

Formed much like a butted seam, except the seam is brazed together with a solder alloy. May be used with solid or stranded wire and can be crimped on any side of the barrel without opening the seam.

Seamless Connectors

Generally only available for a butt connector or splice. The barrel is created from one seamless piece of metal. This eliminates problem of the barrel opening. May be used with solid or stranded wire.

Brazed Seam & Seamless Connector Advantages

• Better wire contact

• Less voltage drop

• Increases current flow

• Superior tensile strength

• Prevents wiring failures

• Reduces equipment downtime
