TOYOSEAL Processing

Prevents dirt on reinforcement thread

Hermetical sealing of hose edge face prevents fluid from seeping into reinforcement thread and protects the thread in hose tip portion from dirt.

Reduces contamination of products

With no fluid seeping into reinforcement thread, products are less susceptible to contamination. Also, sanitary management in factories and processes is facilitated. TOYOSEAL is registered with the FDA, Drug Master File Type II (number 25486). Please read the below precautions before use.
