Mr. Steam Sealant Tube RTV Silicone provides a professional-grade, waterproof seal designed to protect steam systems from leaks, moisture intrusion, and thermal stress. Formulated for high-heat, high-humidity environments, this premium silicone maintains flexibility and adhesion where conventional sealants fail. Ideal for sealing gaskets, joints, and fittings, it forms a resilient barrier that prevents steam loss and corrosion, extending the life of key components and finishes. The easy-apply tube format allows precise control for clean seams and minimal waste, making it equally effective for routine maintenance or quick field repairs. Lightweight at just 1 lb, it’s convenient to carry and deploy in tight service spaces. Trusted across both residential and commercial Mr. Steam installations, this RTV silicone ensures lasting watertight integrity and efficient performance in demanding steam environments.

  • Premium silicone seal – High-quality silicone provides superior sealing in high-moisture, high-heat steam environments, maintaining elasticity and compression set over time. Reliable material resists hardening and micro-cracking, preserving watertight integrity and protecting adjacent components from corrosion and electrical issues.
  • Versatile, waterproof barrier – Ideal for sealing joints, gaskets, and incidental leaks around steam hardware, forming a flexible membrane that accommodates movement. Broad utility supports routine maintenance, reducing seepage paths that waste energy and degrade finishes within the enclosure.
  • Precise, clean application – Tube format enables controlled beads and spot fills in tight spaces, minimizing waste and cleanup. Accurate placement improves first-try results, shortens service time, and yields professional-looking seams that resist snagging or premature peel in wet areas.
  • Stable adhesion through swings – Maintains a strong bond across temperature and humidity changes, resisting shrinkage and loss of grip during thermal cycling. Durable adhesion keeps seals intact between inspections, reducing callbacks and extending intervals between maintenance touch-ups.
  • Lightweight, service-ready – Weighing just 1 lb., the tube is easy to carry in a tool pouch for on-the-go repairs. Portable packaging supports quick, opportunistic fixes that prevent small leaks from becoming costly downtime or finish damage.
