FAQ
How does the Stillson self-tightening mechanism work?
The Stillson pipe wrench has an angled upper jaw that pivots slightly. When you apply torque to turn the pipe, the jaw pivots and bites harder into the pipe surface, increasing grip force automatically. The harder you pull, the tighter it grips. To release, simply reverse the direction and the jaw releases automatically.
What size pipe wrench do I need?
For residential plumbing (1/2 to 1 inch pipes), use an 8-10 inch wrench. For commercial plumbing (1 to 2 inch pipes), use a 12-14 inch wrench. For industrial pipes (2-4 inches), use an 18-24 inch wrench. Always use the smallest wrench that fits the pipe to avoid over-tightening and damaging fittings.
Will the wrench teeth damage the pipe surface?
Yes, the serrated teeth are designed to bite into the pipe surface for maximum grip. This will leave marks on the pipe. For chrome-plated or visible pipes where surface damage is unacceptable, use a strap wrench instead. For underground or hidden pipe work, the Stillson wrench provides the best gripping power.
How do I maintain the pipe wrench?
Clean the jaw teeth regularly with a wire brush to remove debris. Apply light oil to the adjustment nut thread and jaw pivot to maintain smooth operation. Store in a dry environment to prevent rust. If the jaw teeth become worn or rounded, the jaw can be replaced on most professional-grade wrenches.
