Flex-Fill, 18, 24, 36, 48 or 60 inch (45.7, 61.0, 91.4, 121.9, or 152.4 cm) with MH-300 Pressure Gauge

A favorite among glider pilots. This 1/8 NPT-M fitting will screw into any of our pressure regulators or valves that have a gauge port.
This allows the cylinder to now be serviced and pressure monitored from a remote location. May be purchased with or without gauge.
Available is various lengths.

Flex-Fill systems make it easy to fill a remotely mounted oxygen cylinder.  It is an extension line that plugs into the pressure gauge port on the regulator and brings a fill nipple and pressure gauge out to a more convenient location.  It is ideal for use in gliders where the cylinder is mounted in a difficult to reach location. Our integrated fill-stations feature the Swagelok system for the best seal between tubing and fitting. They also have SAE straight-thread with o-ring ports that allow for the most dependable seal.

The free end has an MS22066 male fitting with 3/8-24 thread.  The TA-380-N or TA-380-S transfill adapters work with this fitting.
Note:  All complete EDS system kits include a cylinder with gauged valve and a regulator that does not have a gauge.  The Flex-Fill normally threads into a pressure gauge port on a regulator that would include a pressure gauge. Since standard EDS systems include a regulator without a gauge (and gauge port) the regulator must be upgraded to include a version with a gauge port.  For example, an XCR regulator must be upgraded to an XCR-G (MH-00REG-1030-00-Upgrade, $35).  The upgraded regulator does not include a pressure gauge because the gauge is included with the Flex-Fill.  The price of the upgrade is the price difference between the 2 regulators, minus $25 for the gauge that is not needed.  This upgrade will be added when you order a Flex-Fill unit along with an EDS system.
