⚡ At a Glance
- • Sealing Performance: Rubber stopper creates a tight, leakproof seal for small openings, with heat-insulating properties
- • Best for: Owners of small hot water bags, doll collectors and users needing compact replacement stoppers
- • Not ideal for: Very large hot water bottles with wide necks where small stopper size will not fit
Rubber sealing plugs are anti-ageing and tasteless, designed to reduce heat loss. Compact dimensions of 4.00 x 2.50 x 2.50 cm suit small sacks and miniature bottles.
Reliable leak prevention, with rubber sealing plug
Compression-fit rubber plugs create a physical barrier against water escape, the flexible material conforms to irregular necks while maintaining a tight seal. Anti-ageing rubber resists brittle failure after repeated heating cycles.
Secure, repeatable sealing removes the need for makeshift closures, preventing spills when filling or storing hot water bags.
Improved heat retention, with heat-insulating rubber material
Rubber used here exhibits low thermal conductivity, reducing the rate of heat transfer at the bottle opening. The stopper's bulk and fit cut down convective heat loss from the neck.
Hot water stays warmer for longer around the cap area, giving longer useful warmth from each fill.
Space-saving convenience, with compact 4.00 x 2.50 x 2.50 cm size
Small, lightweight plugs occupy minimal storage space and are easy to keep as spares. The two-piece set provides an immediate replacement and a spare for routine use.
Easy to store in a drawer or travel kit, suitable for small hot water bags and doll or miniature bottles.
