21087716 Retainer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Retainer - Part Number: 21087716

Brand-new genuine Volvo Penta double-head retaining strap used in the factory air-compressor and auxiliary-system installation on the TAD1643VE-B. The moulded retainer secures paired hoses or cables at a fixed spacing so vibration cannot pull them into the compressor drive, hot surfaces or adjoining hydraulic components.

• Used in the TAD1643VE-B air-compressor and auxiliary hydraulic installation

• Factory spacing controls hose movement without crushing the line
