About TopLine Machinery

At TopLine Machinery, we believe that hard-working Americans shouldn't have to overpay to keep their equipment running at peak performance. As a family-owned American company, we have made it our mission to engineer and manufacture premium hydraulic quick-connect couplings, mounting systems, and machinery accessories that deliver ultimate durability without the high price tag.

By stripping away unnecessary corporate overhead and building direct relationships with world-class manufacturing partners, we pass the savings straight to you. We build our products for those who build, farm, and get things done.

Hydraulics to a Higher Standard

Whether operating a Bobcat, John Deere, CAT, Kubota, CASE machine or more, you cannot afford unexpected downtime caused by component failure. Light-duty parts simply won't cut it in rugged conditions.

That is why TopLine products are engineered for maximum reliability:

• Heavy-Duty Build: Heavy-duty carbon steel and advanced Zinc-Nickel plating ensure maximum corrosion resistance.
• Leak-Free Performance: Flush-face and agricultural poppet designs minimize fluid loss and prevent system contamination.
• High-Pressure Ratings: Built to safely handle demanding setups with options rated over 5,000 PSI.
