Our products, which can be found worldwide, are supplied to major exploration and production, equipment fabricators, and petrochemical plants. Norman Filters is the trusted name in quality high-pressure filtration assemblies. Norman Filter Company is a certified AS9100 Aerospace filter manufacturer that brings quality and tested products to the oil and gas industry.

Norman Filter Company has designed, built, and tested a series of B31.3 / ASME Sec. VII Div. 1 design compliant high-pressure assemblies for oil and gas applications requiring a specific design standard. Along with our standard product offering NFC manufactures and supplies T-Type assemblies with Grayloc and flange connection interfaces for offshore platform use.

The oil and gas industry is divided into three major sectors: upstream, midstream, and downstream. The downstream sector is the refining of petroleum crude oil and the processing and purifying of natural gas, as well as the distribution of products derived from crude oil and natural gas. The downstream sector reaches their consumers through products such as but not limited to gasoline, kerosene, jet fuel, diesel oil, heating oil, fuel oils, lubricants, waxes, asphalt, natural gas, and liquefied petroleum gas (LPG) as well as hundreds of other oils and gases.

All retail outlets such as gas stations are included in the downstream sector of the industry. At oil refineries, the crude oil that has been transported via pipeline from upstream operations is converted into useable forms including gasoline, diesel, and even propane. Oil and gas products are even used to aid the process of making artificial limbs, hearing aids, and flame-retardant clothing to protect firefighters. Fun fact, paints, dyes, fibers and just about anything that is manufactured has some connection to oil and natural gas.

Norman Filter Company offers a variety of T-Type and Inline configurations to fit in just about any space or design requirement. Our standard filters are available in:

  • Aluminum
  • Brass
  • 303 stainless
  • 316 stainless steel
  • Duplex steel (2205 Duplex S.S. per ASTM A276)
  • Super Duplex (Super Duplex per ASTM A479)
