Flanges, Gaskets, Nuts & Bolts

Working Parts

Flanges, gaskets, nuts and bolts are small working parts of the overall component system, but they play a crucial role in proper system and equipment function. Careful selection of these components is the best way to ensure reliable seals. Baelz NA stocks all of the flange, gasket, bolt, and nut sizes you might require, and we offer quick delivery within the United States and Canada. We also offer copper components for chemical plant applications upon request.

DIN FLANGES

Flanges are available in 2 standard pressure ratings – DIN flanges use PN16 and PN40 however a lot of flanges now use PN40 for PN16 since the dimensions and patterns are exactly the same.

DIN GASKETS

Gasket sizes and pressure ratings helps to ensure seal integrity and longevity. Gaskets provide a leak-free seal between valve and flange. Graphite or Spiral Wound Options are available.

Selecting components that have the proper fitment is essential to creating a cohesive seal.
