Inspection, Exclusion, and Removal



HVAC and industrial setups can't afford leaks—duct flanges or line fittings that fail spike energy bills or halt production, and codes demand non-toxic, compliant materials. GasketNow assesses your flange photo or CAD file, then laser-cuts white silicone or cork composites that seal tight without off-gassing or cracking under 200°F cycles.
Our advantage is on-demand U.S. fabrication—no bulk minimums or 6-week leads from overseas mills. For contractors facing job-site deadlines or factories with 24/7 runs, we deliver 48-hour batches with exact hole patterns, blending food-grade for kitchens or graphite for high-pressure lines, all verified for ASTM compliance.
Forget the pain of mismatched flanges or toxic residue complaints—we pre-test for 99% first-fit and offer free tweaks, ensuring your system runs efficient and your client doesn't call back for leaks. It's the reliability that keeps HVAC installs on schedule and industrial lines profitable.
