Transform Your Frac Operations with FET's DuraLine™ Manifold System
Speed. Safety. Simplicity.

FET’s DuraLine Manifold is transforming how you rig up and rig down during pad moves by saving time, reducing risk, and maximizing uptime.
Why DuraLine? Because Every Minute Counts.
Traditional API iron setups are heavy, labor-intensive, and prone to leaks. The DuraLine Manifold changes the game with a modular, lightweight, skid-based design that rigs up in under five minutes with just one operator.
Key Advantages That Set FET Apart
Modular Efficiency
Each DuraLine skid can be scaled easily to match any job size with both two-port and four-port cross options. There are no more overbuilt or underpowered setups. You get the right fit, every time.
DuraLock™ Connector Technology
Our hub-style DuraLock connectors use only four bolts per connection — compared to the industry-standard 16. Plus, the elastomeric seal eliminates metal-to-metal contact, drastically reducing leak potential and installation complexity.
One-Person Rig-Up with Ajax™ Crane
Every manifold comes standard with FET’s manifold-mounted Ajax™ crane, enabling a single operator to rig up without forklifts or extra crew. That means fewer injuries, faster deployment, and lower labor costs.
Serpent Series™ Hose Integration
Paired with our Serpent Series hoses, the DuraLine system is 60% lighter than traditional manifold setups, which makes transport, handling, and rig-up safer and more efficient.
Get to Pumping Faster — and Safer
With FET’s DuraLine Manifold System, you’re not just upgrading equipment, you’re upgrading your entire frac operation. Less downtime. Fewer leaks. Lower risk. More revenue.
