Lid with Breather – Pressure-Regulated Tank Sealing
The Hercules Plastics lid with breather is a heavy-duty tank fitting designed to regulate pressure and airflow in sealed or semi-sealed tank systems. Manufactured from high-quality polyethylene, it offers outstanding chemical resistance and long-term durability in harsh outdoor or industrial environments.
The integrated breather allows for controlled ventilation to prevent vacuum lock or over-pressurisation while minimising the risk of external contaminants. This design is ideal for tanks used in chemical dosing, rainwater harvesting, or storage of volatile or temperature-sensitive contents.
Part of our trusted Hercules Tank Fittings range, this lid is precision fabricated for a secure, leak-free fit. It's compatible with a wide range of HDPE tanks and bunded enclosures.
