Connectors, Couplings & Hoses

FPI’s line of oxygen connectors and couplings are widely used in both military and commercial applications, ranging from mask hose and quick-disconnect interface connections to Anti-G suit connectors and metered couplings.

A wide variety of our connectors serve as an integral part of military oxygen distribution systems and are manufactured in accordance with equally demanding military specifications.

MS22058 series
Regulator Hose End Connectors

Manufactured in accordance with
   MIL-C-19064

Female connector typically used in
   conjunction with FPI’s line of
   MS22055 oxygen hoses providing
   quick disconnect capabilities between
   diluter demand mask and regulator.

Two Styles - FPI part number 4085
   (MS22058-1) includes connector with
   spring loaded cover to prevent
   contamination while not in use and a
   clip mechanism for securing the
   assembly as needed. FPI part
   number 4090
(MS22058-2) includes
   the cover assembly without the clip.

Bodies are nickel plated brass for
   improved durability.

Mates with MC-3A, MC-3M, CRU-60/P,
   CRU-94/P, MIL-C-83867, and AN
   safety type connectors

Mask Hose End Connectors

Connecting the mask to the regulator hose or oxygen source can be accomplished through various methods depending on the desired system. FPI has a number of options available to
meet those needs.

For applications requiring bailout capabilities, the most common system is comprised of
  two connectors. FPI part number 1675 is a 3-pin bayonet connector manufactured per
  specification MS27796 and secured directly to the diluter demand mask hose. This
  connector couples with a CRU-60/P interface connector, FPI P/N 6200, with a quick
  disconnect design allowing emergency egress from the aircraft along with a safety valve
  which provides notable resistance to inhalation in case inadvertent disconnection occurs.
  The 6200 construction incorporates a secondary inlet that will attach to the bailout oxygen
  assembly to provide the pilot with oxygen during descent and includes a dove tail
  mounting plate. When attached to FPI’s P/N 1636 mounting bracket (AF 57B3657), this
  plate provides secure mounting of the connector to the parachute harness. The 6200 is
  manufactured in accordance with MIL-C-38271 and has been approved by the U.S.
  Government per QPD-38271.

Bailout requirements can also be met using FPI part number 1450 (MC-3A). Qualified by
  the U.S. Government and manufactured per QPD-19264, MS22016-1 and MIL-C- 19246,
  this component was the predecessor to the CRU-60/P. It attaches directly to the diluter
  demand mask, thus eliminating the need for the MS27796 connector, while providing the
  same quick disconnect element and bailout system connection. Unlike the CRU-60/P, the
  positioning of the bailout connection is stationary, thus limiting placement of the
  emergency oxygen system. Alternate part number 4875 (MC-3M) is available providing
  180 degree positioning of the bailout connection.

FPI P/N 2765 may be used in applications designed to mate with the MS22058 female
  connector while not requiring a bailout oxygen system. Using the same proven quick-
  disconnect and safety valve technology; this connector creates a maximum pressure drop
  of .07” W.C at 30 lpm flow when attached to the MS22058 female connector. Replaces
  Scott model 7025 and B/E model 118030.

Anti-G Suit Hose End Connectors

FPI part number 5440 is
  manufactured in accordance with
  MIL-C-83390 and designated
  MXU-636/P. A quick-acting, male
  connector designed and tested for
  use with anti-g garments such as
  CSU-13BP and CSU-15AP, it provides
  controlled inflation, deflation and
  pressure relief characteristics. The
  mating connector for this product is
  MS27755, FPI part number 5348.

Also available to support select
  international military requirements is
  the legacy connector MS22011-3. Ask
  for our P/N 4615.

Plug-In Couplings and Outlet Assemblies

Fluid Power manufactures a number of commercial plug-in connectors and outlet assemblies
designed to deliver metered, constant flow requirements.

Model 890 Series – ARO Type automatic female coupling provides metered delivery of
  oxygen. Flow rates are achieved through adjustable porous media ranging from .5 to 8.0
  LPM. Provides 1/8 NPT male connection with bulk head cap and dust cover. Similar to Scott
  P/N 5041 and B/E P/N 170088. Mates with FPI P/N 2305 mask connector with 1⁄4” barb.
  (Sierra P/N 289-56, Scott P/N 29559 and B/E 119030)

Model 4240 Series – AN6009 type outlet, typically found on therapeutic and portable
  oxygen systems, can supply similar adjustable flow rates between .5 and 8.0 LPM.
  (Comparable to Scott P/N 5009 and B/E P/N 170086.)

FPI P/N 4195 – Manufactured in accordance with Mil-Spec M7560/1-20, this nonmetered
  plug-in connector is found in many commercial and military applications ranging from
  emergency drop-down mask assemblies to bail-out and portable oxygen systems. A mate
  with AN6009 type outlets such as FPI P/N 4240, it provides a 1⁄4” barbed connection for
  use 3/16” flexible tubing. (Comparable to Scott P/N 5065-10, Sierra 777-37 and
  B/E 118040)

FPI has numerous other common and legacy connectors available for your oxygen delivery
needs. Contact us to learn more.

MS22055 Mask to Regulator
Hose Assemblies

Manufactured per MIL-H-81581, this hose provides connection between the mask hose and regulator. Constructed of wire reinforced fabric with an ozone resistant liner and molded ends, hoses should be ordered to specific lengths as required. Hoses are sold separately (“H” style) or in “A” or “B” styles as noted below. Both comprise of a hose and MS22058 connector with spring loaded dust cover. “A” styles include integrated high-tension mounting clip. This is replaced on “B” styles by an included retainer strap.
