The Air Selector Valve is a two position on/off valve that selects between two different pressure or vacuum sources to run instruments on an aircraft.
MOUNTING BASE BRACKET
The Mounting Base Bracket is designed as a mount for liquid oxygen converters and OBOGS systems in aircraft. Made of corrosion resistant steel. Hole placement can be modified to meet specific customer requirements. Conforms to MS90341.
CRYOGENIC HIGH PRESSURE CLOSING VALVE
Cryogenic High Pressure Closing Valves are designed for use on Air Force and Navy liquid oxygen converters as well as other cryogenics systems with operating pressures of less than 300 PSIG. The pressure closing valve allows the cryogenic system to maintain operating pressure while in use.
CRYOGENIC LOW PRESSURE CLOSING VALVE
Cryogenic Low Pressure Closing Valves are designed for use on Air Force and Navy liquid oxygen converters as well as other cryogenics systems with operating pressures of less than 130 PSIG. The pressure closing valve allows the cryogenic system to maintain operating pressure while in use.
LOX DRAIN VALVES
LOX Drain Valves are designed for use with the Air Force and Navy liquid oxygen converters. The drain valve allows the LOX system on-board an aircraft to be completely drained.
HYDRAULIC PULSATION DAMPENERS
Hydraulic Pulsation Dampeners (or attenuators) are designed to reduce fluid pressure pulsations generated by aircraft hydraulic pumps. These pulsations can lead to system damage through check valve failure, tubing or hose rupture, loosened connections and cracked manifolds. In addition to the potential for system failure, hydraulic pressure pulsations can dramatically increase noise levels within the aircraft cabin. Unlike nitrogen-charged “muffler” devices, Essex hydraulic pulsation dampeners contain no moving parts and require no servicing. Constructed of high-strength 15-5PH hardened steel, these units are subjected to non-destructive tests prior to shipment.

GASEOUS OXYGEN QUICK DISCONNECT COUPLING
The Gaseous Oxygen Quick Disconnect Coupling allows for the rapid disconnect and connection of aircraft LOX converters to enable servicing. This coupling is designed in accordance with MIL-C-21049.
FUEL EJECTOR PUMP
This Fuel Ejector Pump features an integral check valve which prevents fuel from draining back into the tank when the system shuts down. The inlet fitting on the pump is designed for a 5/8″ line, with the outlet port sized for a 1″ line. The fuel ejector pump has a 94% efficiency.
FLAME ARRESTORS
Flame Arrestors are designed to allow for the venting of fuel vapors while preventing external flames or other ignition sources from entering the fuel lines and supply. Essex flame arrestors are installed in all Boeing commercial aircraft, as well as a number of regional aircraft.

F-15 BORESIGHT REFERENCE UNIT
The F-15 Boresight Reference Unit is an optical alignment device that is mounted on the upper right side of the F-15 instrument panel. The BRU works in conjunction with the Joint Helmet-Mounted Cueing System (JHMCS) and allows the Weapon Systems Officer (WSO) to align his or her aiming reticle, projected on the helmet visor, with the aircraft’s targeting sensors. This capability allows both crew members to track and lock on to targets simultaneously, particularly with high off-boresight weapons.
