KTI 8181-14-K 14-Quart Rectangular Poly Hydraulic Reservoir Kit — OEM Replacement

The KTI 8181-14-K is the factory OEM replacement reservoir kit for KTI hydraulic pump power units requiring a 14-quart poly tank. The 8181 series uses a rectangular flat-sided body profile — the same form factor as the common KTI 8181-6 (6-quart) and 8181-35 (3.5-quart) reservoirs. The 8181-14-K is the largest reservoir in the 8181 series, providing nearly 2.5× the fluid capacity of the standard 6-quart unit. Ideal for high-demand dump trailer applications, extended duty cycles, or system upgrades where heat management and fluid volume are a concern.

Sold as a complete kit — includes the tank, hardware, breather, and seal. Drop-in replacement with no modifications required.

📐 Specifications

Specifications per KTI Hydraulics Inc. official 2024 catalog. 8181-series — same body profile and mounting pattern as 8181-6 (6-quart) and 8181-35 (3.5-quart). Longest 8181-series reservoir available.

🔍 Why Replace Your Reservoir?

Common reasons for reservoir replacement on KTI dump trailer hydraulic systems:

• Cracked or cloudy tank — UV exposure and impact can crack poly over time, leading to leaks or contaminated fluid
• Contaminated fluid — water intrusion or debris ingestion often warrants a full tank swap with fluid change
• Capacity upgrade — swapping to a larger reservoir reduces operating temperature on high-cycle commercial applications
• System rebuild — full pump overhaul or motor replacement is a natural time to replace the reservoir

💪 Key Features

✔ High-Grade Polypropylene Construction

KTI's poly tanks resist hydraulic fluid, UV degradation, and impact. The translucent material allows visual fluid level inspection without removing the cap — a practical advantage over steel reservoirs.

✔ OEM KTI — Drop-In Fit

Engineered to KTI's factory specifications. Mounts directly to the pump assembly without modification. The 4-bolt flange pattern matches the existing pump tower footprint.

✔ Integrated Dipstick Breather Cap

The included filler/breather cap features an integrated dipstick for accurate fluid level checking. The breather function prevents vacuum lock and contamination during pump operation.

✔ Complete Hardware Kit

Every component for a clean installation is included. No hardware runs to the hardware store — this is a complete replacement kit.

📦 Kit Contents

• Poly reservoir tank
• 3/4" NPT reservoir fill/drain plug
• Filler breather cap with integrated dipstick
• Reservoir O-ring seal (pump-side gasket)
• (4) mounting screws

Everything needed to replace a reservoir on an existing pump — no additional hardware required.

⚠ Compatibility Note

KTI uses multiple reservoir body profiles across their pump lineup. Verify your pump assembly's reservoir series (8181-series) and mounting pattern before ordering. If unsure, call us at (517) 225-1991 and we'll confirm fitment against your pump's model number.
