All Promax diesel tanks have plenty of safety, strength and reliability built into them. That’s because we use tough diesel grade polyethylene in every tank. This material complies with the chemical and mechanical resistance requirements of International Regulations ECE R34.01. In other words, it ensures every tank will give you years of maintenance-free life with no worries about secure and dependable diesel storage around the home, on the farm, or in any industrial setting. Diesel tanks in New Zealand don’t come any better than this.
