The LOCTITE 135506 is an RTV silicone joint sealant supplied in an 80 mL tube. It cures at room temperature to form a flexible, durable silicone seal suitable for potting, sealing, and gasketing applications across HVAC, plumbing, and general mechanical assemblies. The compound reaches a tack-free state in 30 minutes and achieves full cure in 24 hours. The white color makes it easy to identify bead placement during inspection. Technicians working on enclosures, junction boxes, and mechanical assemblies rely on this sealant for fast, reliable sealing without the need for mixed or heat-activated compounds.
This sealant is well suited for potting applications in electrical and mechanical assemblies, as well as sealing joints and gaps in HVAC equipment, plumbing fixtures, and general trade applications. The 80 mL tube format is practical for single-use or small-batch jobs where a full-size cartridge is unnecessary. It is appropriate for both residential and light commercial work and is installed by HVAC technicians, plumbers, and electricians as part of routine service or new installation work.
Designed for use as a general-purpose RTV silicone joint sealant in potting, sealing, and gasketing applications across HVAC, plumbing, and electrical assemblies.
Apply to clean, dry surfaces free of oil, grease, and loose debris for best adhesion. Power down or de-energize any electrical enclosures before applying sealant in or around live components. Allow the sealant to reach full cure at 24 hours before exposing the joint to fluids or mechanical stress. Installers should follow applicable codes including NEC for electrical enclosure work and IFGC or IPC for plumbing and HVAC applications where sealants are used at joints.
