KPALAG Aluminum Oil Bath Cap Wrench for Dexter Axles — 2-1/2" Hex, Fits Drum 8-415 & 8-430, 1/2" Drive

Designed for trailer owners, mechanics and fleet managers, this wrench replaces OE K71-704-00-style tools and is sized specifically for Dexter drum numbers 8-415 (post–July 2009) and 8-430 (post–April 2013). Machined from anodized aluminum, it balances light weight with durability for routine hub maintenance, allowing use with a 1/2" driver ratchet or breaker bar.

How does this wrench match my Dexter axle oil bath caps?

This KPALAG wrench is manufactured to the same fit dimensions as the OE K71-704-00 cap tool and maps directly to the Dexter drum part numbers listed. The hex dimension and seating face are made to align with the cap profile so you get consistent engagement.

• Compatible with Dexter Drum 8-415 (after July 2009)
• Compatible with Dexter Drum 8-430 (after April 2013)
• Designed to OE K71-704-00 fit and form

What size driver do I need and how is it used?

The tool accepts a standard 1/2" driver ratchet or breaker bar and presents a 2-1/2" (63.5 mm) hex interface. To use, align the wrench over the oil bath cap, seat it fully, and apply steady torque with your 1/2" drive—no special adapters required.

• 2-1/2" (63.5 mm) hex for 1/2" drive tools
• Works with ratchets, breaker bars or torque tools with 1/2" drives
• Simple align-and-seat operation for quick service

Is the wrench durable for shop and field use?

KPALAG builds this cap wrench from anodized aluminum to resist rust while keeping overall weight low for hand and overhead use. The anodized finish increases surface hardness and helps prevent corrosion from road salt and grease, but users should still store it dry and avoid impact damage.

• Lightweight aluminum construction for easier handling
• Anodized surface for improved hardness and corrosion resistance
• Precision-machined for consistent seating and reduced slippage

What comes in the package and will it work with other hubs?

The product ships as a single KPALAG aluminum axle hub oil bath cap wrench intended for the specific Dexter cap profiles listed. While designed for those Dexter drum numbers, verify cap geometry before assuming fit on other manufacturers' hubs.

• Package includes: 1 × KPALAG aluminum oil bath cap wrench
• Intended for specified Dexter drum numbers; check cap shape for other brands
• Not a multi-size adapter — made to fit the listed caps precisely

Who is this for? Trailer owners, service technicians and fleet operators who perform routine axle hub maintenance and need a reliable, lightweight tool that matches Dexter oil bath cap dimensions. If you maintain trailers with Dexter 8-415 or 8-430 drums and want a corrosion-resistant wrench that works with common 1/2" drive tools, this KPALAG wrench is a practical replacement for worn or missing OE cap tools.
