Description
Product Overview
High-pressure systems need controlled downstream pressure without sacrificing shutoff performance or serviceability. The TESCOM 44-1116-24 is a brass pressure-reducing regulator in the 44-1100 Series, designed for high-pressure, low-flow applications. Its published configuration has a maximum inlet rating of 6,000 psig (414 bar) and an adjustable outlet range of 50–6,000 psig (3.4–414 bar). The regulator uses a piston-sensed design and includes inlet and outlet gauge ports, allowing technicians to monitor pressure on both sides during setup and troubleshooting.
The regulator is intended for systems such as ground support equipment, pressure panels, aircraft charging carts, calibration equipment, and research laboratories. Its venting function allows downstream pressure to be released through the regulator’s vent path as the setting is reduced. The manufacturer-family specifications also describe a removable valve assembly, a low operating torque, and bubble-tight leakage performance. Actual performance depends on the configured pressure range, medium, installation, and maintenance condition. The model’s brass body and wetted materials must be checked for compatibility with the process gas or fluid; a pressure rating alone does not establish suitability for every medium.
For procurement and maintenance, the TESCOM 44-1116-24 should be selected against the required inlet pressure, downstream setpoint, flow demand, connection standard, and media compatibility. Its published flow coefficient is Cv 0.06, indicating that it is intended for low-flow service rather than unrestricted high-volume delivery. Confirm the precise regulator configuration and outlet-range designation before ordering. For oxygen service or other applications with special cleanliness requirements, verify the cleaning standard and material suitability with the responsible system designer. The supplier documentation lists CGA 4.1 and ASTM G93 cleaning, but the specific service requirements must still be checked against the installation.
Product Introduction
A regulator operating near 6,000 psig needs to match the system’s pressure range, flow demand, and wetted-material requirements. The TESCOM 44-1116-24 combines a brass body, piston sensing, venting capability, and a low-flow design for high-pressure pressure-control systems.
Before installation, verify the outlet pressure requirement, 1/4-inch NPTF connection, media compatibility, and safe vent routing. Do not select this model solely because its maximum pressure rating matches the supply pressure.

Frequently Asked Questions
Q1. What is the TESCOM 44-1116-24 used for?
It reduces and controls downstream pressure in high-pressure, low-flow systems. Listed applications include ground support equipment, pressure panels, aircraft charging carts, calibration equipment, and research laboratories.
Q2. Can it handle an inlet pressure of 6,000 psi?
Its published maximum inlet rating is 6,000 psig (414 bar). That rating does not mean every downstream setpoint, fluid, temperature, or installation is suitable. Verify the complete system design and applicable pressure requirements before use.
Q3. Is the outlet pressure adjustable?
Yes. The published outlet range for this model is 50–6,000 psig (3.4–414 bar). Confirm that the required setpoint falls within this range and that the system’s flow demand is appropriate for the regulator’s Cv of 0.06.
Q4. Can I use this regulator for oxygen service?
Do not assume it is suitable for oxygen merely because supplier documentation lists cleaning to CGA 4.1 and ASTM G93. Oxygen service requires verification of material compatibility, cleanliness level, system design, and applicable safety requirements by a qualified specialist.
Q5. Does the regulator vent downstream pressure when the setting is reduced?
The 44-1100 Series is described as a venting regulator that can release downstream pressure through its vent path. The vent must be routed safely for the process medium and operating environment. Confirm the exact configuration and follow the installation instructions.
Q6. How often should the regulator be serviced?
Supplier guidance recommends regular servicing, typically annually under normal usage. Actual intervals should reflect the medium, duty cycle, contamination risk, operating conditions, and manufacturer instructions. Use only the approved service parts and lubricant specified for the regulator.
Q7. What should I confirm before purchasing a replacement?
Check the complete model number, brass body configuration, maximum inlet pressure, outlet range, 1/4-inch NPTF ports, and wetted-material compatibility. Request confirmation of the actual unit’s condition, available documentation, warranty, and return terms. For safety-critical pressure systems, have the intended application reviewed by a qualified pressure-system engineer before installation.
