No More Hydraulic Headaches in the Field – This Agricultural Coupling Just Works

2026-04-02

If you have ever been in the mud, trying to change a hydraulic line on a tractor or log splitter, you know the drill. Leaks, spills and fittings that will not come loose. That’s exactly why we’re excited about our CNV push-and-pull type hydraulic quick couplings – because farming and forestry equipment shouldn’t come with a side of frustration.

What Makes the CNV Different?

First, it’s designed to withstand abuse. The CNV series is constructed of high-strength carbon steel with a zinc-plated finish that is resistant to dirt, moisture and the everyday wear and tear of farming and forestry applications.

But the real magic is in the design. This is a true non-spill coupling—both sides seal immediately when you disconnect. No drips, no wasted oil, no slippery mess on your gloves. That's what turns it into a dependable non-spill coupler for anyone who considers time and equipment to be well spent.

And because we know you’re not running a museum, the CNV follows ISO 5675 – the standard for Agricultural Coupling systems. It is also interchangeable with ISO 7241-1 A type, allowing it to be used with a variety of existing hydraulic tools and attachments. Need male orfemale hydraulic coupler fittings? We have them both, and they are designed to fit perfectly.

Where Does It Shine?

We see the CNV making a real difference in three main areas:

🚜

Agricultural machinery – tractors, harvesters, irrigation systems. A dependable agricultural coupling keeps your operation moving during planting or harvest season.

🌲

Forestry equipment – log splitters, wood chippers. These machines see heavy loads and harsh conditions. The CNV delivers the durability you need.

🏗️

Material handling – loaders, forklifts. Secure Hydraulic Connections are essential for safe and efficient lifting.
