Vacuum Resin Infusion Line Clamp for 1" Hose SQ-100

Vacuum Resin Infusion Line Clamp – SQ-100 (for 1" hose OD)

The SQ-100 is a professional, saddle-style line clamp designed for precise flow control and quick clamping of resin and vacuum lines in infusion and other composite processes. Its fine-pitch adjustment lets you regulate, throttle, or fully shut off flow with minimal effort, while the open saddle makes it easy to position and remove on the fly. Built for daily shop use, the clamp delivers repeatable control and reliable holding power on large hoses up to 1.0" OD.

Key Features

• Fine adjustment: screw/knob mechanism allows exact regulation of resin or vacuum flow.
• Fast clamping: saddle design slips under the line for quick placement and removal.
• Rugged: engineered for daily professional use in demanding, industrial conditions.
• Low effort: requires only minimal force to clamp or release.
• Versatile: ideal for disconnecting, throttling, or shutting off flow on a wide variety of tubing.
• Handcrafted in the USA.

Compatibility & Sizing

• Model: SQ-100 — fits tubing with outer diameter up to 1.0".
• Also available: SQ-60 for outer diameters up to 0.6" (sold separately).
• Use with typical infusion and vacuum lines (polyethylene, vinyl, polyurethane, etc.). Verify tubing wall and hardness for best results.

Typical Uses

• Resin infusion (VARTM): feed-line throttling, balancing multiple inlets, or emergency shut-off.
• Vacuum plumbing: isolating manifolds, catch-pot service, and line disconnects.
• General composites shop flow control on larger-OD flexible hoses.

Good Practice

• Place the clamp on straight sections of tubing; avoid sharp fittings/edges under the saddle.
• Increase pressure gradually when throttling; do not overtighten beyond shut-off.
• Confirm material compatibility with your resin system and solvents.
