The 3M Littmann Stethoscope Spare Parts Kit (Model 40017) in Gray is an essential maintenance solution designed to extend the lifespan and preserve the exceptional acoustic performance of your diagnostic equipment. Specifically engineered for medical professionals, clinics, and hospitals across India, this versatile kit provides genuine replacement components for three of Littmann's flagship models: the Classic III™, Cardiology IV™, and the CORE Digital Stethoscope. Instead of replacing an entire instrument due to routine wear and tear, this kit allows doctors, nurses, and medical students to quickly restore their stethoscope to its original, factory-standard precision.

This comprehensive gray maintenance kit is purpose-built for seamless compatibility and easy on-site installation within busy hospital wards, clinics, or home healthcare settings. It includes a single-piece tunable diaphragm assembly for both the adult and pediatric sides of the chestpiece, along with an aesthetic gray rim to ensure a completely airtight seal. Additionally, the kit features two snap-tight, soft-sealing eartips that conform comfortably to the user's ear canals, maximizing external noise isolation and ensuring crystal-clear sound transmission during critical patient examinations.

Key Benefits:

Multi-Model Compatibility: Perfectly fits 3M Littmann Classic III, Cardiology IV, and CORE Digital stethoscopes, eliminating the need to buy separate kits for different models.
Cost-Effective Maintenance: Saves money by allowing you to easily replace individual worn-out parts instead of investing in an entirely new stethoscope.

Enhanced Comfort: Includes premium, soft-sealing eartips that provide a comfortable fit for prolonged usage while effectively blocking ambient clinic noise.
Original 3M Quality: Contains 100% genuine Littmann components, ensuring the exact same durability, materials, and color match as your original device.

How to Use ( Littmann® Stethoscope Spare Parts Kit )

Step 1: Remove the Old Parts: Gently peel off the worn-out diaphragm assembly and rim from the stethoscope chestpiece. If replacing eartips, pull them firmly to snap them off the eartubes.
Step 2: Clean the Surface: Wipe down the chestpiece edges and eartube ends with a 70% isopropyl alcohol wipe to remove any accumulated dust, oils, or residue before installing new parts.
Step 3: Install the New Diaphragm: Take the new single-piece gray diaphragm assembly and fit its groove over the edge of the chestpiece. Work your way around the perimeter until it sits smoothly and securely without buckling.
Step 4: Attach the Eartips: Push the new gray soft-sealing eartips firmly onto the ribbed ends of the eartubes until they click completely into place.
Step 5: Test the Performance: Lightly tap the newly installed diaphragm while wearing the headset to confirm an airtight seal and clear sound transmission.

Safety & Maintenance Information:

Regular Inspection: Periodically check the diaphragms and eartips for signs of cracking, hardening, or tears to ensure your diagnostics remain accurate.
Correct Sizing: Verify your stethoscope model name before installation, as this kit is uniquely sized for the Classic III, Cardiology IV, and CORE series.
Firm Attachment: Always ensure the eartips are snapped all the way onto the headset to prevent them from coming loose inside the ear canal during use.
Storage Warning: Store any unused spare parts in a cool, dry place away from direct sunlight, chemical solvents, and extreme heat to prevent material degradation.
