Bellows, Seals and Breathing Circuit Consumables for GE Anesthesia Machines: Capsule 1500-3378-000, U-Cup 1500-3359-000, APL Diaphragm 1406-3331-000
GE breathing circuit consumables: capsule 1500-3378-000, U-cup 1500-3359-000, APL diaphragm 1406-3331-000, O-ring seals and condenser 1407-3133-000-S.
A breathing circuit leak is the most common cause of "floating" problems on an anesthesia station: the machine runs, but it does not hold pressure, the circuit test does not pass, and the anesthesiologist adjusts ventilation parameters manually. In most cases the culprit is not an expensive assembly but a consumable element: a seal, an APL diaphragm, a bellows cuff or a gasket.
This guide covers twelve consumable and wear items of the GE breathing circuit that have entered the MediAccessori catalog. For each item the official catalog description, compatible equipment, an approximate price in rubles and stock availability are given.
1. How breathing circuit tightness is built up
The tightness of an anesthesia machine is provided by four groups of elements:
- •bellows (folding capsule) — the working element of the ventilator that moves the breathing mixture;
- •seals — rings and cuffs that close the joints of assemblies under pressure;
- •APL diaphragm — the moving element of the pressure limit valve during manual ventilation;
- •gaskets and auxiliary parts — secure the assemblies and protect them from displacement and overheating.
Of this set, only the bellows costs noticeable money. Everything else is inexpensive consumables, and downtime caused by their absence costs more than a year's supply of them.
2. Bellows: folding capsule 1500-3378-000
No official catalog description is provided for this item; the purpose is a folding capsule (bellows) for a GE anesthesia machine, compatible equipment — GE anesthesia machines.
Approximate price: 17,600 ₽ · Availability: 10 pcs.
The bellows is a wear element: the folds of the material work cyclically, so over time microcracks and leakage through the capsule body appear. Symptoms — a pressure drop during ventilation, unstable tidal volume, noise during machine operation. Availability of 10 pcs. is intended for scheduled replacement in several machines at once.
3. Diaphragm and seat sub-assembly 1500-3377-000
Official catalog description (English): The Diaphragm & Seat Sub-Assembly is a component of breathing circuit gas system used to regulate the pressure in the breathing circuit. The pressure relief valve assembly provides accurate pressuring while ventilating a patient with the use of diaphragm. The amount of pressure buildup in the bellows should be limited and also gases are to be released for scavenging. For adjusting these pressure limits, a diaphragm and seat subassembly are used as a part of pressure relief valve assembly. These are being used in MS CARESCAPE™ Monitor B650, ARC iCentral, MS Dash™ 4000, ARC Aestiva 7100, MS PRN50 Writer, ARC Airway Gas Module, ARC iVent 201, ARC Testing Service, MIC Giraffe™ Warmer, ARC Aestiva 3000, MS CIC Pro, ARC Anesthesia Monitor, MIC Panda™ iRES Warmer, ARC Aespire 7100, MS Solar 8000, ARC Airway Gas Module, ARC iVent 201, ARC Testing Services, MS CO₂ MODULE, ARC Monitor CardioCap 5, MS CIC Pro v5, ARC Aestiva MRI, ARC Engstrom Carestation, ARC Aestiva 7100, ARC Aisys, ARC Monitor, ARC S/5 Monitor FM, ARC Airway Gas Module, ARC S/5 Monitor Anesthesia, ARC ADU, ARC Monitor CardioCap 5, ARC Airway Gas Module, ARC Light Monitor, ARC ADU, ARC MRI Monitor, ARC Aestiva 7100, ARC Aespire 7900, ARC Tec 6 Plus and ARC Aespire View.
Equipment: Aespire · Approximate price: 11,000 ₽ · Availability: 10 pcs.
According to the official description, the diaphragm and seat sub-assembly is part of the breathing circuit pressure relief valve assembly and is used to adjust the limit pressure in the circuit. If the circuit test fails on pressure retention, this assembly and the APL diaphragm are checked first.
4. Bellows and circuit seals
PN 1500-3359-000 — bellows U-cup seal
Official catalog description (English): SEAL U-CUP ABA
Equipment: Aestiva · Approximate price: 8,580 ₽ · Availability: 10 pcs.
The cuff seals the bellows along its edge: this seal works in a compression and extension cycle, so it is replaced together with the bellows or at the first sign of leakage.
PN 1503-3208-000 — O-ring
Official catalog description: PART, O-RING 34.59ID 39.83 BCG OD 2.62 W EPR 60 DURO, Injection molded
Equipment: GE Datex Ohmeda · Approximate price: 1,320 ₽ · Availability: 10 pcs.
PN 1407-3104-000 — seal ring
Official catalog description: PART, O-RING OD30 ID22 4W BCG SILICONE 40 DURO, Injection molded
Equipment: Aespire · Approximate price: 1,320 ₽ · Availability: 10 pcs.
PN 0210-0463-300 — O-ring
Official catalog description: PART, O-RING .562ID .750OD .093W SILICONE 45-55DURO
Equipment: tied to the oxygen sensor (the card lists the "oxygen sensor" section). Approximate price: 1,320 ₽ · Availability: 20 pcs.
PN 1102-3016-000 — seal ring
Official catalog description: ASSY-MSN, KIT SPARE O-RING VLV PORT STEETON NO 46147
Equipment: other anesthesia machines (Anesthesia Other) · Approximate price: 1,320 ₽ · Availability: 20 pcs.
Four rings at 1,320 ₽ each are the most cost-effective reserve in the selection: they cover different machines in the fleet, and their availability in stock eliminates downtime caused by a missing consumable. Separately, note the difference in dimensions and materials given in the official descriptions: the rings are not interchangeable, select by PN.
5. APL diaphragm 1406-3331-000
Official catalog description (English): DIAPHRAGM APL BCG
Equipment: Aestiva · Approximate price: 1,650 ₽ · Availability: 10 pcs.
The APL valve (adjustable pressure limit) limits the pressure in the breathing circuit during manual ventilation, and its diaphragm is a consumable element that works with the gas flow and breathing mixture. Wear shows up as impaired pressure retention, unstable pressure gauge readings and characteristic leaks.
At a price of 1,650 ₽ the diaphragm is worth keeping in permanent reserve: it is replaced as routine, not as a repair.
6. Soda lime: gasket 2105489-001
Official catalog description: 40 pcs. per pack ("Pack of 40 pcs." — translation of the original card description.)
Equipment: for soda lime canister 1407-7004-000 · Approximate price: 6,600 ₽ · Availability: 20 pcs.
The foam gasket of the soda lime canister secures the canister and protects it from displacement and vibration. Availability of 20 pcs. and a pack of 40 pcs. are intended for a fleet, not for a single machine.
7. Auxiliary circuit assemblies
PN 0229-2080-100 — sight glass plug
Official catalog description (English): OEM, PLUG SIGHTGLASS
Equipment: Aestiva · Approximate price: 1,320 ₽ · Availability: 10 pcs.
A damaged sight glass plug is a frequent cause of a small but constant leak that is hard to localize, because it is not related to either the bellows or the valves.
PN M1171751-S — elbow connector
Official catalog description (English): Elbow Connector 1/8"inch 3.2mm Inner Diameter (ID)
Equipment: 9 Series -ACS (anesthesia machine) · Approximate price: 2,200 ₽ · Availability: 5 pcs.
The elbow connector belongs to the pneumatic lines of the breathing circuit: if the joint loses tightness, a leak appears in the pressure measurement line.
8. Condenser 1407-3133-000-S
Official catalog description (English): Tube Assembly Breathing Circuit Gas (BCG) Mechanical
Equipment: GE Aespire · Approximate price: 88,000 ₽ · Availability: 10 pcs.
The most expensive item in the selection — a breathing circuit tube assembly in mechanical design. The explanation is simple: the assembly is built from many joints and seals, so it is replaced by condition rather than by calendar, and is kept in reserve for a group of machines.

10. Typical breathing circuit faults
- •The circuit test fails on pressure retention — check the bellows (1500-3378-000), the bellows cuff (1500-3359-000) and the diaphragm and seat sub-assembly (1500-3377-000).
- •Pressure during manual ventilation is not limited correctly — check the APL diaphragm (1406-3331-000) and the pressure relief valve assembly.
- •A slow leak that cannot be localized — check the rings (1503-3208-000, 1407-3104-000, 0210-0463-300, 1102-3016-000) and the sight glass plug (0229-2080-100).
- •A leak in the pressure measurement line — check the elbow connector (M1171751-S).
- •The soda lime canister shifts and vibration appears — check the gasket (2105489-001).
- •A leak through the body of the circuit tube assembly — check the condenser (1407-3133-000-S).
The diagnostic order is from cheap to expensive: rings, diaphragm, plug, bellows cuff, bellows, tube assembly.
