Key Features & Benefits
Factory Precision Fit: Molded to exact OEM dimensions to guarantee a seamless, leak-proof seal on the UNS Delta 120 canister head and valve assemblies.
High-Grade Elastomeric Rubber: Flexible, durable rubber compound resists drying out, hardening, or cracking under constant water pressure and chemical exposure.
Restores Vacuum & Prime: Prevents micro air leaks that cause noisy impeller air pockets, rattling motors, and loss of pump siphon strength.
Protects Cabinet Flooring: Eliminates slow, hidden drips and seal bypass to safeguard your aquarium stand and living space from water damage.
Essential Annual Maintenance Upgrade: Keeping a spare seal kit on hand ensures zero downtime during routine filter cleanings or emergency seal replacements.
Technical Specifications
Always apply a thin layer of aquarium-safe silicone lubricant to new O-rings and main head gaskets during installation to maximize seal life and prevent pinching.
