Wacker Neuson 5000157881 St. #8 Orb #8 Orfss Fitting

The Wacker Neuson St. #8 Orb #8 Orfss Fitting is a genuine OEM hydraulic fitting designed for WB16A and WB16AE series Power Buggies. Sourced directly from Wacker Neuson, this fitting is manufactured to the same standards as the original component installed at the factory, ensuring a correct, leak-free connection in the hydraulic circuit. Part number is compatible across a wide range of WB16A variant models, including electric-start, front-steer, and combination configurations.

Key Features

• Genuine OEM Hydraulic Integrity — Manufactured to original Wacker Neuson specifications, maintaining correct thread form, port sizing, and sealing geometry for a leak-free hydraulic connection.
• Direct-Connect Replacement — Threaded to match the original O-ring boss (ORB) and O-ring face seal (ORFSS) port configuration, allowing straightforward installation without reworking adjacent lines or fittings.
• Broad WB16A Series Compatibility — Fits WB16A, WB16AE, WB16AF, WB16AS, WB16AEF, WB16AES, WB16AFS, and WB16AEFS Power Buggy variants across multiple serial ranges.
• Prevents Hydraulic Fluid Loss — A damaged or worn fitting can cause hydraulic fluid leaks that reduce system pressure and impair the buggy's dumping and drive performance; replacing it promptly restores full hydraulic function.
• Verified Part Number Traceability — Ordering by Wacker Neuson part number 5000157881 confirms you are receiving the exact fitting specified for your machine's hydraulic plumbing layout.

A hydraulic fitting serves as the threaded connector between hydraulic hoses, lines, and ports within the Power Buggy's hydraulic system. The O-ring boss and O-ring face seal thread types used on this fitting create a metal-to-metal seating surface backed by a compressed O-ring, providing a more reliable seal under pressure than tapered thread designs. When a fitting cracks, strips, or corrodes, hydraulic fluid can escape at the joint, causing pressure loss that affects the buggy's ability to raise and dump its load — making prompt replacement essential for continued operation.
