5″ (125 mm) straight hemostats clamp model airplane fuel lines or aquarium tubing securely without damage. A must-have tool for hobbyists.

Model airplane and RC hobbyists rely on precision tools to keep engines running smoothly. A 5″ (125 mm) straight hemostat makes an excellent fuel line clamp, providing secure grip without crushing or damaging delicate tubing. Whether you are setting up nitro engines, troubleshooting fuel delivery, or making quick adjustments at the flying field, this compact tool gives you the control and reliability you need.

These hemostats (locking forceps) are made with AISI 420 German surgical grade stainless steel, not "alloy steel" recovered from rusted cars. See "Documentation" for the chemical analysis certificate.

Best Practices for Using Hemostats in Fuel Line Clamping

  • Choose the right size: A 5? (125 mm) straight hemostat fits most model airplane and aquarium tubing.
  • Clamp gently: Use the first or second ratchet click to stop flow without over-crushing tubing.
  • Inspect tubing: Check regularly for wear or cracks caused by repeated clamping.
  • Keep clean: Wipe down after contact with fuel to prevent residue buildup.
  • Use as a temporary stop: Hemostats are best for short-term clamping during setup, testing, or repair — not as a permanent fix.
  • Store in your kit: Keep a pair in your field box or toolbox for quick fixes on-site.
