Ring Terminal 14-16 AWG F21

The Ring Terminal (part# F21) is a genuine Tacony OEM replacement part for the Tornado CK 3030 wide-area vacuum (Model 93030). This Ring Terminal is a closed-loop crimp connector sized for 14-16 AWG wire and a No. 10 stud; the ring slips over a screw or stud and is clamped down, making a secure connection that cannot slip off like a spade can.

Compatible Models for the Ring Terminal

• Tornado CK 3030 Wide Area Vacuum (Model 93030) — Series D through J

This is a shared Tacony wide-area-vacuum part and fits additional Tacony models beyond the 93030. We have not published its full compatibility list, so call 763-535-0770 to confirm the exact part for your machine.

A Ring Terminal is chosen where a connection must not vibrate loose, since the fastener passes through the closed ring. Failure is usually at the crimp or from corrosion. Signs it needs replacing are a loose or pulled-out crimp where the wire meets the ring, a cracked or broken ring, corrosion or heat discoloration on the terminal, or an intermittent connection at the stud it lands on. Replacing it re-establishes a solid, captive connection. It is crimped to the wire and secured under its screw or stud during an electrical repair.

Twin City Vacuum has been selling and servicing Tacony equipment since 1956 and stocks the genuine F21 part rather than a generic substitute. Browse the full Tornado CK 3030 wide-area vacuum for related parts, or read more on the Tornado manufacturer site.
