We understand that unique tanks require unique manways, which is why we offer customized specifications such as: pressure ratings, extended collar lengths, material types, lift/spring assist, CRNs and more.
Depending on your industry, tanks can vary in design and size, that in turn can affect the style of manway needed for the job. That's why we carry over 30 options including; round, oval, rectangle, and cone shaped. Whether it's an atmospheric cross-arm manway or a 13 lug, high-pressured T-bolt style manway, we have something for your application.
A new design recently introduced to the market, the Mueller Lift Assist, differs from original "spring assist" manways in that it uses nitrogen cylinders that allow the user full control while accessing the inside of their tank. Click the link below to see its functionality.

Different jobs have different needs, that is why we offer a variety of material types for your manway. Our most common material types are 304 or 316 stainless options, with sanitary applications often requiring 316 material. For more corrosive jobs, you might find the need for something more exotic such as duplex or hastelloy. Job's requiring visual inspection can easily be accomplished with a Mueller glass manway.
