Sella Plus K11®
Premium HVAC-R sealant for FLANGES, CONNECTIONS, and GASKETS, guaranteeing absolute sealing and the most precise vacuum on the market.
SELLA PLUS K11® was developed with a high-performance formulation to meet the demands of AC-R air conditioning and refrigeration systems, including automotive applications. Its ultra-viscous composition prevents drying, crystallization, or permanent adhesion, differentiating it from conventional chemical sealants (threadlockers) or glues. It has lubricating power on parts and components made of rubber, silicone, and elastomers, preventing drying and extending their lifespan.
Designed for critical system points — flanges, joints, connections, o-rings, Schrader valves, compressor joints, hose connections, manifolds, recyclers and vacuum pumps — SELLA PLUS K11® ensures complete sealing, stability under thermal variations and vacuum maintenance with maximum precision.
This performance significantly reduces the occurrence of micro-leaks, eliminating rework and installation returns caused by sealing failures in flanges.
It has lubricating power for parts and components, such as o-rings or sealing rings, made of rubber, silicone, elastomers, preventing drying and extending their lifespan.
Fully compatible with all coolants and lubricants, SELLA PLUS K11® is certified by ASHRAE – Protocol 97, ensuring chemical stability and complete system protection.
