U-115 Series T-Type Filter
The U-115 Series is a mil-spec-engineered, high pressure filter housing built for low-flow, high-pressure fluid and gas filtration applications — most commonly deployed across the Oil & Gas industry. Machined from 316 Stainless Steel (SS) or 17-4 PH SS, this T-type filter housing is engineered to hold pressure ratings up to 20,000 PSI while maintaining a controlled 7.5 GPM flow rate, making it one of the most robust stainless steel filter housings in Norman Filter Company's product line.
The U-115 Series filter housing is ideal for protecting critical components in offshore, subsea, and petrochemical environments across the globe, where failure is not an option and equipment must withstand extreme pressure, temperature, and corrosive conditions.

Why Choose the U-115 Series High Pressure Filter Housing
Norman Filter Company manufactures the U-115 Series in-house at our Bridgeview, IL facility, giving customers full control over material, port configuration, and element selection:
-
316/316L Stainless Steel — Offers strong corrosion resistance for standard oil & gas and industrial applications.
-
17-4 PH Stainless Steel — Provides higher tensile strength for extreme-pressure, high-cycle applications where added durability is critical.
-
FNPT Female O-Ring Medium Pressure Ports — Engineered for a secure, leak-resistant seal in high-pressure line connections.
-
Bypass valves, visual/electrical indicators, and bowl drain ports — Available as accessories to support system monitoring and maintenance.
Every U-115 Series housing is proof and burst pressure tested, helium leak tested, and bubble point tested in-house before shipment, ensuring each unit meets the same rigorous quality standards required for aerospace and mission-critical oil & gas systems. Learn more about our testing capabilities.
Common Applications
The U-115 Series high pressure filter housing is built to perform in some of the most demanding environments in the world. Common applications include:
-
Sub Sea Tieback Systems — Protects hydraulic and chemical injection lines in subsea tieback and TLP (tension leg platform) systems, where filter reliability directly impacts uptime in remote, hard-to-access installations.
-
Chemical Injection Units — Filters methanol, corrosion inhibitors, and other chemical injection fluids used in hydraulic wellhead control systems across the oil & gas industry.
-
Aerospace Ground Support Equipment — Supports fluid filtration for ground support equipment used by both public and private aerospace programs, backed by our AS9100D certification.
-
High Pressure Gas Filtration — Delivers reliable particulate control in high-pressure gas lines across petrochemical and industrial processing facilities.
-
Pump-Motor Packages — Protects pump-motor package components from contamination in high-pressure hydraulic circuits.
These applications reflect just a few of the industries Norman Filter Company serves — see our full Industries Served for more on our work across Oil & Gas, Aerospace, Military/Marine, and Alternative Fuel markets.
Frequently Asked Questions
What is a T-type filter used for?
A T-type filter is a high-pressure filter housing shaped like a "T," allowing inline installation in tight spaces while housing a removable filter element. T-type filters like the U-115 Series are commonly used in oil & gas, subsea, and aerospace ground support systems requiring reliable, low-flow, high-pressure filtration.
What pressure rating can the U-115 Series filter handle?
The U-115 Series high pressure filter housing is rated between 6,000 and 20,000 PSI, depending on configuration. It's engineered with high-strength 316 or 17-4 stainless steel housings to maintain structural integrity in extreme-pressure oil & gas, subsea, and petrochemical applications.
What materials are used in high pressure filter housings?
High pressure filter housings are typically made from 316/316L or 17-4 PH stainless steel for corrosion resistance and strength. Norman Filter Company's U-115 Series uses both alloys, selecting 17-4 SS for higher tensile strength in extreme-pressure or high-cycle applications.
What micron ratings are available for high pressure filtration?
High pressure filtration systems like the U-115 Series support micron ratings from .2 to 200 nominal (300 absolute), using elements such as cellulose, glass fiber, stainless steel wire mesh, random metal fiber, or porous sintered media, depending on the required particulate control level.
What industries use high pressure T-type filters?
High pressure T-type filters are widely used in oil & gas (subsea tieback systems, chemical injection units), aerospace ground support equipment, and petrochemical processing. Norman Filter Company's U-115 Series is engineered specifically to meet the demanding pressure and reliability requirements of these industries.
