Stop oil vapor weeping and crankcase contamination with our Premium 3979593 (1676319) Engine Oil Filler Caps for VOLVO EC210B, EC240B, and EC380E excavators. Get direct factory pricing, bulk B2B discounts, and fast global air express shipping from China's leading mechanical parts networks supplier today!
Seal Your Crankcase, Protect Your Lubrication. Damaged filler cap causes oil vapor leakage and external dust invasion, contaminating engine oil and abrading internal moving parts. This heavy-duty threaded cap tightly seals crankcase opening, isolating pollutants and maintaining normal lubrication environment for Volvo excavators.
Fiber Reinforced Polymer Body Anti high temperature aging, impact and crack damage under harsh working conditions.
Deep Anti-loosening Thread Perfect match original oil filler neck, avoid looseness and falling off under long engine vibration.
Fluorocarbon Sealing Ring Excellent oil corrosion resistance, keep stable sealing elasticity against high temperature oil gas.
Anti-slip Hand-tight Design Easy installation and disassembly, realize reliable locking sealing without auxiliary tools.

Oil filler cap is easily lost and damaged daily maintenance part. Poor sealing leads to oil deterioration and accelerated component wear. Global wholesalers and mine warehouses shall stock genuine 3979593 caps. Combine with housing gaskets, intake gaskets and cooling pressure caps to enrich upper engine spare parts inventory.
Oil vapor leaks out around cap, dust adheres and forms greasy dirt on engine surface
Cap thread cracked or clamping lug broken, unable to lock tightly with filler port
Visible blow-by gas escapes from gap during idling, sealing performance declines seriously
All models for compatibility reference only. Effective sealing filler cap keeps crankcase clean, avoids oil contamination, and greatly reduces abnormal wear failure of internal engine parts.
