3x4 Hydraulic Cylinder Double Acting Cross Tube - Heavy Duty 3500 PSI

In this review of the 3x4 Hydraulic Cylinder from AMRAP HYDRAULICS the bottom line is clear: this compact cross tube cylinder is best for owners of front-end loaders and tractors who need a strong, straightforward replacement cylinder. The reviewer found it excels at delivering reliable force in a small package thanks to a 3 in bore and 4 in stroke paired with a 3500 PSI rating, so it performs well for lifting and loader duties where a robust, universal-fit cylinder is required.

Key Features

• 3 in Bore, 4 in Stroke: Provides a compact yet powerful working travel that fits many loader applications while delivering predictable movement.
• 3500 PSI Rated Pressure: High working pressure gives consistent lifting force and enough margin for heavy loader tasks up to the stated column load capacity.
• All-Welded Heavy-Duty Construction: Durable steel body and welded cross tube resist impact and harsh outdoor use for longer service life.
• SAE 8 Ports with O-ring Boss: Standard hydraulic ports simplify hookup and reduce the chance of leaks when installed with compatible fittings.
• High-Quality Compact Seals: Seals are designed to limit leakage and keep out rust particles, helping the cylinder maintain performance in dirty conditions.
• Universal Fit Compatibility: The cross tube design is intended to integrate with front-end loaders from many leading brands as an affordable replacement option.

Who It's For

This cylinder suits farmers, landscapers, and contractors who maintain small to mid-size tractors and front-end loaders and need a direct, cost-effective replacement part. It is particularly useful for those who appreciate a compact retracted length (12 in) and do not require long travel.

It is less suitable for bespoke or specialty hydraulic systems that need custom ports, exotic materials, or longer strokes; buyers seeking stainless or corrosion-free marine-grade cylinders should look elsewhere.
