It carries the legacy part number CC129-1A-2, so if you're replacing that older reference, this is the direct drop-in. This is a consumable accessory — the damping film sits between the transducer and the pipe wall to improve acoustic coupling and reduce signal noise. You'll need it when reinstalling transducers after maintenance or on a new pipe spool. It ships as a single piece, one unit per order. Group code R3P3, product group 4727 — those are Siemens internal classifications that won't affect your BOM line, but they confirm this is the correct accessory family for the FS220 meter. ## Compliance note One thing to flag for your compliance docs: this product is not RoHS-compliant. If your project requires RoHS exemption declarations or full material disclosure, you'll need to account for that. REACH Article 33 candidate-list information is available from Siemens upon request. Export control is straightforward — AL: N, ECCN: EAR99I, so no special licensing for most destinations.","metaTitle":"Siemens 7ME3960-0DM20 SITRANS FS220 Pipe Damping Film, Activ","metaDescription":"Siemens 7ME3960-0DM20 pipe damping film for SITRANS FS220 ultrasonic flowmeter D1/D3 transducers.
