Thread-Seal Tape
Known as Loctite 55, Forwa 55, etc., the cord is a high-strength composite fiber core wrapped in an inert sealing adhesive and dry lubricant. It’s not glue, not tape— it’s a “smart rope” that Rope-like Smart Sealing Element.
Loose threads? Leaky joints? Painful reinstalls? One cord seals them all—permanently.
I. The Pain Points: Why traditional sealing methods fail
Still battling these headaches?
❌ One nick in the threads and it leaks: PTFE tape demands perfect threads; the smallest scratch kills the seal.
❌ No post-install adjustment: Torqued it half a turn too far? Rip it off and start over—wasting time and labor.
❌ Vibration loosens fittings: Water hammer or machine shake breaks the seal; you’re back on the job site.
❌ Plastic & stainless threads won’t grip: Smooth surfaces let tape slip, driving failure rates sky-high.
❌ No way to plug leaks under pressure: Shutting down the line for a re-wrap costs a fortune.

III. Five Reasons Pros Are Ditching Tape Forever
50 % faster installs
No counting wraps—wind 3-8 turns (per size) and tighten. Built-in cutter in a pocket spool; one-hand, no-mess, works in the rain.

Adjustable sealing—world’s first
Even after full torque you can back off ¼ turn to fix alignment or length errors without breaking the seal. Install tolerance jumps from 10 % to 90 %.

Seals where tape gives up
• Damaged or odd-shaped threads: liquid-like flow fills nicks and dents.
• Plastic & stainless: lubricated surface bites and never slips.
• Live leaks: wrap over a weeping joint, tighten, done—no shutdown.
