The Clear RTV Silicone Sealant 66B designed by Permatex® is the perfect solution to fixing the cracked or undone sealant around your spa assembly parts and jets. This spa adhesive sealant from Permatex® will bond and seal frayed edges. This is the perfect adhesive as it is waterproof, weatherproof, flexible, and can be used in temperatures ranging from -75° to 400°F.
Is the sealant around your jets or other assembly parts coming undone? You’re not alone; this happens all the time and the sealant simply don’t last as long as everyone believes it should. But, seeing as some of the assembly parts to your spa are exposed to wind, rain, direct sunlight — not to mention high humidity from your spa — the sealant generally does a decent job of standing up to the abuse.
