Our Suppliers

Quality Products

All of our manufacturers are subject to the same rigorous approval and audit processes, which allow us to deliver quality products that meet customer form, fit, and function requirements at the lowest total costs of ownership. Take advantage of our large inventory of fittings and flanges and our ability to inventory and stage customer-specific items to simplify your procurement and project materials management.

Carbon Steel and Low Temp Fittings and Flanges

We continually strive to be the premier supply chain solutions provider of fittings and flanges, and our preferred manufacturers can be found on the approved manufacturers lists (AMLs) of all major energy companies. We provide pressure and weld fittings, flanges, swages, and pipe nipples. We also inventory high-quality domestic and import fittings and flanges from 1/4 in through 36 in. Larger sizes are available on request.

High Yield Fittings and Flanges

DNOW has always distinguished itself from competitors by providing extra value to customers, and we continue this tradition by taking a strong position on supplying hard-to-find high yield fittings and flanges. We inventory 4 in through 30 in fittings and flanges, in 42,000 psi through 70,000 psi minimum yield material grades. Our High Yield Program provides fittings with properties beyond the requirements of national standard MSS-SP-75. Fittings furnished from our inventory meet the following criteria:

  • Lower carbon equivalent for greater weld-ability
  • All elbows (LR and 3R) suitable for field segmenting
  • All fittings 16 in and larger meet impact requirements for low temperature service

These properties represent an added value available at no cost to our customers.

Stainless Steel Fittings and Flanges

We are able to supply all grades of stainless and high-nickel alloys from the most reliable manufacturers in the world. Our inventory includes high quality stainless steel pressure and weld fittings, flanges, swages, and pipe nipples from approved manufacturers in all shapes and in sizes ½ in through 12 in. Stocked grades include 304/L, 316/L, and duplex grade UNS32205.

Resin-Based Fittings

We stock a wide range of fiberglass and polyethylene fittings.

Gaskets and Stud Bolts

DNOW offers spiral wound, ring-type joint (RTJ), sheet, and heat exchanger gaskets, as well as a variety of fastener and stud bolts in various material grades and coatings. We provide a wide range of bolting products in black carbon steel, stainless steel, plated, and Teflon-coated.
