SECURE. RELIABLE. BUILT TO LAST.

We manufacture only from the highest-quality materials to ensure our hatches seal tighter and require less maintenance than those of the competition.

Ideal for use on steel or fiberglass oilfield storage tanks, our hatches securely seal tanks while providing customized pressure and vacuum relief, and easy access to tank contents for level gauging and sampling.

Regardless of industry, application or environmental regulation standard, our hatches have you covered.

IT'S ALL IN THE NAME.

It's easy to buy cheap components from second-rate wholesalers, stamp a name on them and list them at a markup – and some companies do exactly that.

It's a lot tougher to design the product in-house, manufacture it in your own facility, then test and fine-tune to perfection before putting it on the market. But we do. Because we know your system relies on us – so we'll only put our name on products you can trust.
