Olympus A5857 Sealing Cap (Red) — 10pcs/bag, Flexible Endoscope Air/Water & Suction Channel Seal
Olympus · Medical Endoscope Consumable · In Stock
The Olympus A5857 is an OEM red silicone sealing cap designed for
Olympus flexible endoscope air/water and suction channel nozzles,
used to maintain channel integrity during manual cleaning, automated reprocessing (AER) and clinical use. Sold as
10pcs per bag for GI labs, bronchoscopy suites, ERCP rooms and hospital sterile processing departments.
KOEED’s core is industrial automation — Allen-Bradley,
Siemens,

Application Scenarios & Where It Fits
The Olympus A5857 is deployed in clinical environments where flexible endoscope reprocessing volumes are high and a
reliable red sealing cap is part of the standard workflow. Typical settings include:
-
Gastrointestinal (GI) endoscopy units — gastroscopy and colonoscopy rooms running Olympus GIF / CF series scopes
-
Bronchoscopy suites — pulmonary diagnostics on Olympus BF-series flexible bronchoscopes
-
ERCP rooms — endoscopic retrograde cholangiopancreatography on Olympus JF / TJF duodenoscopes
-
Hospital Sterile Processing Departments (SPD) — high-volume reprocessing between cases
-
Ambulatory surgery centers — outpatient endoscopy with daily scope turnover
-
Biomedical engineering workshops — in-house repair benches where a worn cap is replaced before scope return-to-service

Hospital procurement teams often bundle clinical consumables like the A5857 with the same RFQ that covers factory-floor spare parts.
Integration & Compatibility Notes
The A5857 is a purely mechanical consumable — there is no electrical wiring. The cap press-fits onto the
distal-end air/water nozzle of an Olympus flexible endoscope and forms a fluid-tight seal that prevents leakage of irrigation
water, escaping insufflation pressure and cross-contamination between channels. Compatibility is therefore driven by scope
model family and nozzle geometry rather than voltage or signal interface.
| Scope Family |
Olympus GIF (gastroscope), CF (colonoscope), JF / TJF (duodenoscope), BF (bronchoscope) — EVIS EXERA / EXERA III / LUCERA / LUCERA ELITE generations
|
| Processor / Light Source Pairing |
Olympus CV-260 / CV-290 video processors and CLV-260 / CLV-290 light sources — cap is scope-side, not processor-side
|
| Distinguishing Feature |
Red color coding differentiates A5857 from black or blue cap variants used on different scope generations — do not substitute a different color onto a red-coded nozzle
|
| Adjacent Consumables |
Olympus biopsy forceps, cleaning brushes, suction valves, biopsy port caps, water-jet adapters — typically consolidated on the same procurement cycle
|
| Do Not Substitute |
Use only the red A5857 cap on red-coded Olympus nozzles. Universal third-party caps can compromise channel pressure-test results during AER validation
|
Engineers familiar with
Siemens SIMATIC S7-300 I/O or
Allen-Bradley 1756 rack systems
will recognize the same plug-and-seat philosophy — a consumable must match the connector or nozzle it seats against.
Cross-reference the Olympus cap color code with your scope’s IFU before ordering.

Installation & Handling Tips
-
Inspect on receipt. Open the bag in a clean area and confirm ten red caps are present, free of visible tears, hardening or surface tackiness from age.
-
Match the cap to the scope. Confirm the Olympus A5857 red cap matches the color code on your scope’s air/water nozzle. A mismatch can break the pressure-test step inside your AER cycle.
-
Seat on a clean, dry nozzle. Wipe the nozzle with a lint-free pad moistened with instrument-grade detergent, allow it to dry, then press-fit the cap straight on — no twisting, no lubricant.
-
Single-use discipline. The A5857 is a disposable consumable. Treat it as single-use per reprocessing cycle, even if it appears visually clean — silicone relaxes with thermal cycling.
-
Leak-check before clinical use. After seating, run the scope’s built-in leak test (or the AER pre-cycle pressure test). Replace the cap if the test fails before any patient contact.
-
Storage. Keep unopened bags sealed at room temperature, away from UV, ozone-generating equipment and concentrated disinfectant fumes that can age the silicone.
-
Bulk handling. For multi-bag orders, rotate stock FIFO (first-in, first-out). Olympus A5857 lot codes are printed on each bag — record them with your SPD traceability log.
For plant maintenance teams that also run
Mitsubishi MELSEC or
Yaskawa MP controllers,
the same FIFO discipline applies. A consumable is only as reliable as the lot you pull first.
