Fimco replacement wet boom nozzle assembly 13' coverage — polyacetal end with shut-off valves & swivel (left/right, 1/2" inlet)

The Fimco 7771885 replacement boom nozzle assembly is a durable polyacetal wet-boom end piece with built-in shut-off valves and swivel, designed to restore 13-foot spray coverage and precise liquid delivery on Fimco three-nozzle sprayers.

If a worn or damaged nozzle end is reducing coverage or causing uneven spray patterns, this OEM-compatible Fimco 7771885 (OEM# 5275122) assembly is made to replace the left or right end of wet boom systems. Constructed from polyacetal with polypropylene components and using Hypro-manufactured tips, it offers the components and performance expected for boomless, long-range spraying. The unit accepts a 1/2" hose inlet, measures approximately 3-5/8" x 6-5/8", and includes integrated shut-off valves and a swivel to simplify line management and maintenance.

How does this nozzle assembly restore spray coverage?

Replacing a damaged end nozzle with the Fimco 7771885 returns the boom to its intended 13-foot distribution pattern. The nozzle tip and body geometry are matched to factory specifications to produce consistent droplet size and throw distance when paired with the correct pressure and tip selection.

• 13' designed coverage for long-range boomless spraying
• Tip from Hypro for predictable spray characteristics
• Works as left or right end unit to balance the boom
• Precision fit to Fimco three-nozzle wet booms to reduce drift and gaps

What features make installation and use easier?

The assembly includes user-friendly components to speed installation and field servicing. A built-in swivel helps prevent hose kinks, while integrated shut-off valves allow you to isolate the end nozzle without removing the hose or depressurizing the entire boom.

• 1/2" hose inlet simplifies plumbing to standard sprayer lines
• Built-in shut-off valves let you stop flow at the end for maintenance or transport
• Swivel reduces hose stress and improves durability in tight configurations
• Direct replacement fit minimizes tools and downtime during swap-out

What materials and compatibility should I expect?

The Fimco 7771885 uses polyacetal and polypropylene materials chosen for chemical resistance and wear life in agricultural and landscape spraying. The assembly is designed for use with bottomless (boomless) sprayer setups and uses industry-standard tip designs for compatibility with common operating pressures.

• Polyacetal body for strength and chemical tolerance
• Polypropylene components where light weight and corrosion resistance are needed
• Hypro-sourced tip for industry-standard spraying performance
• OEM number 5275122 cross-reference for correct replacement selection

How should I maintain the nozzle for long life?

Routine checks and simple cleaning keep the nozzle spraying reliably. Flush lines after each use, inspect the tip and valve seats for debris or wear, and replace tip inserts when spray patterns begin to vary.

• Flush with clean water or recommended solvent after each application
• Check valve operation and swivel movement for smooth action
• Replace worn tips or seals to restore pattern and flow rate
• Store assembled or drained in a frost-free area to prevent cracking

Who this is for: the Fimco 7771885 nozzle assembly suits farmers, landscapers, and applicators who need a dependable replacement end for wet-boom or boomless Fimco sprayers. It’s ideal for operators who want a drop-in part with built-in shut-offs and a swivel to reduce hose stress, and for anyone who prefers OEM-compatible components manufactured with industry-standard tips for predictable spray performance.
