Another variety of fastener from Pi-Thon is the Fire Lock, which is basically a big Hose Lock made out of stainless steel and intended for exhaust tubing. The Fire Locks are actually CNC-machined from T-304 stainless, and are offered for tubing sizes from 21⁄2 inches to 4 inches. There are applications to join butt-ended tubes of the same diameter as well Locks for overlapping tubes. Finish choices are between brushed or polished stainless for durability.

The Pi-Thon Induction Lock is a billet aluminum compression fitting that replaces conventional air intake hose clamps. Those unsightly pieces of steel can be forever replaced with this polished piece of ingenuity that offers superior sealing performance due to its compression clamp design. The Pi-Thon Induction Lock also comes in a hi-luster, polished aluminum finish. For more information,
