The Wacker Neuson Lockable IRH Fuel Cap is a genuine OEM component designed for the RD16-90 hydrostatic vibratory roller and CB14B-900 soil and asphalt compaction equipment. As a direct factory replacement, this cap ensures a secure, sealed fit on the fuel filler neck, keeping fuel protected from contamination and unauthorized access on the jobsite. Genuine OEM sourcing means is manufactured to the exact specifications of the original part, giving you a drop-in replacement with no guesswork on fitment.

Key Features

  • Locking Security: — Integrated lock mechanism prevents unauthorized fuel access and deters fuel theft on shared or unsupervised worksites.
  • Contamination Protection: — Tight-sealing design keeps dirt, debris, and water out of the fuel system, protecting injectors and fuel lines from damage caused by contaminated fuel.
  • Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring a correct thread engagement and a proper seal every time the cap is installed.
  • Confirmed Fitment: — Verified for the RD16-90 hydrostatic vibratory roller and CB14B-900 compaction roller — cross-reference part number 5000178721 before ordering.
  • Fuel System Integrity: — A worn or cracked fuel cap allows vapors to escape and moisture to enter; replacing it promptly keeps the fuel system operating at the correct pressure and cleanliness standard.
  • Safety Compliance: — Proper fuel cap sealing is a basic equipment safety requirement; a functioning lockable cap helps meet site fuel-handling and fire-prevention protocols.

The fuel cap seals the fuel tank filler opening and serves two critical roles: keeping the fuel supply clean and maintaining the correct venting balance within the tank. On compaction equipment that operates in dusty, muddy, or outdoor conditions, a degraded or missing cap is a direct path for contaminants to enter the fuel system, which can clog filters and fuel injectors. The lockable feature on this IRH cap adds a layer of access control, making it especially practical for rental fleets or multi-operator job sites where fuel security is a concern.
