Tank manways are a key component in many pharmaceutical, chemical, biotech and food and beverage tanks. Available in low, mid and high pressure applications, the design is excellent for sanitary applications – no crevice for product buildup. Our tank manway flanges are welded with full penetration welds, and our manways and can be manufactured from stainless steel, nickel and specialty alloys such as Hastelloy™, AL6XN, Duplex 2205, and Inconel.

The O-ring gasket is retained in the cover, so it will not fall into the vessel when the manway is opened. Our innovative Spring Assist reduces lifting force, and all-stainless-steel internals ensure the manway operates smoothly.
