Overview
Mountain High makes a variety of oxygen cylinders.  The most popular series is their AL series.  The KF Series weighs about 1/2 as much as the AL series.  However, is quite a bit more expensive, requires recurrent pressure testing every 3 years, and must be replaced after 15 years.

Cylinder Lengths
The Aluminum cylinder lengths shown in the tables below include the cylinder and valve - no regulator.  The added length for a standard XCR regulator is about 1.75 inches (45 mm).
The composite cylinder lengths shown in the tables below include the cylinder only - no valve or regulator.  The added length for a standard US CGA-540 valve and XCR regulator is about 3.5 inches (89 mm).

Cylinder Valve Port Types
There are 2 types of cylinder valve port types commonly used in aircraft.  It is important to know which one is on your cylinder when ordering a regulator for it.  The regulator attaches to this port.

  • CGA-540 - US standard, Approximate outer diameter of threads: 0.875" (22.2 mm)
  • DIN-477 - European standard, Approximate outer diameter of threads: 1" (25.4 mm)

All cylinders provided by Mountain High use 3/4 x 16 UNF threads.  However, 2 different types of o-rings are used - one for aluminum cylinders and a different type for fiber wrapped cylinders.

When ordering cylinder valves, it is necessary to specify the service pressure rating of the cylinder that it will be used with.  Then the correct burst plug can be supplied in the valve.

Description
AL Series Aluminum The AL aluminum oxygen cylinders are featured in our XCP, XCR & EDS portable oxygen systems. These cylinders feature our low-profile CGA-540 (oxygen) valve with pressure gauge that shows the amount in the cylinder at all times with the valve open or closed. Although these aluminum cylinders are intended for portable 'carry-on' applications, they have been used in some airborne applications. See our Full Pack cylinder harness & carry-caddy for these cylinders. Also see CMK cylinder hold-down kits.
CFF Series
 
Aluminum core with
Silica (glass) Fiber Wrap
CFF cylinders have an aluminum core with silica (glass) fiber wrap and are DOT-E 7277-3000 rated. These are high-pressure oxygen cylinders for service pressures up to 3,000 PSI. They can be optionally ordered with a DIN-477 (Euro-norm) valve with gauge.
CFFC Series
 
Aluminum core with
Carbon Fiber Wrap
 
KF Series
 
Aluminum core with
Kevlar Fiber Wrap
The lightest aircraft oxygen cylinder that technology has to offer. These Kevlar fiber-wrapped cylinders have been developed specifically for aircraft use.

The KF series cylinders are the perfect solution for cylinder installations far aft in the aircraft previously not possible before. A thin-wall, seamless aluminum (6061-T6) alloy 'liner-cylinder' is reinforced by a full over-wrapping of Kevlar fibers sealed in epoxy. This yields about a 50% to 60% weight savings over conventional cylinder technology without any compromise in safety.

These cylinders are preferred by many who build the state-of-the-art composite-fiber aircraft. They are made under a DOT mfg. protocol. If used in commercial applications or in a type-certified aircraft, the DOT service life is 15 years from the first hydro-test date and hydro-tests are done every three years. The KF series cylinders are complemented by our RCV/RCR remote-controlled-regulator system and built-in EDS system. The KF series cylinders can be secured for carry-about applications with the Full-Pack and Tuff-Pack cylinder carry-caddy harness systems.


Kevlar Fiber cylinders are the lightest technology has to offer and are designed specifically and approved for aircraft applications. A simplified fabrication process is where the cylinder liner is made (steps 1,2,3 & 4) Fiber wrap (steps 5 & 6) are wrapped around the liner. Threads for the valving device is done after step 4 and before step 5. Epoxy is applied during the wrapping process.

If the cylinder is to be used in type certified aircraft, by current DOT protocol, it must be hydro tested every three years and taken out of service if it fails or after 15 years from the first hydro test date comes about. Even if the cylinder passes hydro test. DOT protocol does not specifically detail any requirements for these cylinders if used in experimental aircraft. As of July of 2006, any Kevlar cylinder tested after that date can be hydro tested every 5 years (instead of 3).  That is true for cylinders manufactured before that date.

Technical Notes
Weight of Oxygen: 0.083 lb/cu. ft.

Oxygen Pressure Ratings
Oxygen cylinders specifications are sometimes shown at 2 different pressures.  The 1850 rating is excellent for comparison purposes and in locations where that is the maximum fill pressure available.  The higher ratings are nice to know but are not available at all oxygen supply locations.

Lead-time
I try to stock as many parts as possible so I can ship to you immediately upon the receipt of your order.  However, MH offers an extremely broad range of products and kits so it is not possible for me to stock everything.  However, it is possible for MH to ship parts I don't have in stock directly to you very quickly.  That is good for you because you receive the products quickly.  It is good for me because it reduces the amount of inventory I need to stock and also eliminates the cost of shipping the products to me.  The items marked "In Stock" below are almost always in my stock here in Minnesota, USA.  The items marked "1 Day" (or similar) can be shipped directly from the vendor in Oregon, USA to you.
