🔧 Product Description

Genuine Volvo Penta nipple of the late type, weighing 0.037 kg and listed for 38 applications across the TMD, BB, DP, SP, MS and TAMD ranges. The late-type designation is what separates it. A second nipple in this run, 856954, sits in the Fuel System group at 0.045 kg for 67 applications - eight grams apart and a different part, so order by number.
