Your Thread Configuration, Verified Before It Ships

The last thing you need on a deployment is a supply line holder that won't mate with your hose. We verify your thread type — NST, NPT, BSP, or CAM — and orientation before the order ships. After purchase, we confirm your spec by email. If your department runs female couplers with outside hose threading, we make sure that's what arrives. No guesswork, no return freight claims, no downtime on the fireground.

Secure Hose Attachment on Any Fol-Da-Tank Frame

Secure Hose Attachment on Any Fol-Da-Tank Frame

This double supply line holder anchors your fire hose directly to the Fol-Da-Tank frame, preventing lateral movement and hose whip during high-volume drafting operations. Built-to-spec for industrial-grade field use, it handles the torque and vibration that come with sustained pump operations. Available in 2.5-inch and 3-inch sizes, it matches your existing supply line diameter without adapters that create failure points.

Four Thread Standards for Department Compatibility

Four Thread Standards for Department Compatibility

Fire departments and municipal water operations don't all run the same fittings. That's why this holder is available in NST, NPT, BSP, and CAM thread types. Whether your apparatus is spec'd with National Standard Thread, National Pipe Thread, British Standard Pipe, or cam-lock couplings, we configure the holder to match your setup. Female orientation — with inside threading — is the most common configuration, but male options are available if your manifold requires it.

Compatibility Check

Confirm these conditions before ordering.

  • Your operation uses a Fol-Da-Tank frame tank
  • You require a 2.5-inch or 3-inch supply line connection
  • Your hose coupling uses NST, NPT, BSP, or CAM threading

“We ordered two of these for our Fol-Da-Tanks after a deployment where a loose supply line caused a drafting interruption. Tank Vault confirmed our NST female thread spec by email the same day. Holders arrived, bolted right up, and the hose didn't budge at 1,000 GPM. Exactly what we needed.”

Frequently Asked Questions

This holder is available in four thread types: NST (National Standard Thread), NPT (National Pipe Thread), BSP (British Standard Pipe), and CAM (cam-lock). After purchase, Tank Vault confirms your required thread type and orientation — male or female — by email before the order is finalized. Female orientation with inside threading is the most common configuration, designed to connect with fire hose that has outside threading.
Yes. The FDT Double Supply Line Holder is designed to attach directly to any Fol-Da-Tank frame tank. It is available in 2.5-inch and 3-inch sizes to match your supply line diameter. Select the size that corresponds to your existing hose configuration, and we confirm the thread specifics after your order is placed.
After you place your order, Tank Vault sends you an email confirming whether you need a male or female thread orientation and which thread type — NST, NPT, BSP, or CAM — your setup requires. This verification step ensures the holder that arrives matches your hose and manifold exactly. No assumptions, no wrong fittings on delivery.
A female supply line coupler has threading on the inside, which connects to a fire hose with outside threading — this is the most common setup in fire department operations. A male coupler has threading on the outside, used when your connection point or manifold requires that configuration. We confirm your required orientation after purchase to prevent mismatches.
This supply line holder is engineered specifically for Fol-Da-Tank frame tanks and is not guaranteed to fit other frame systems without modification. If you are using a different portable tank frame, contact Tank Vault before ordering. We can advise on compatibility or help you source the correct mounting hardware for your specific setup. Do not assume cross-compatibility without verification.
Lead time depends on your confirmed thread configuration and current inventory levels. After we verify your thread type and orientation by email, the order moves into processing. If you have a specific deployment date or deadline, contact Tank Vault with your required specs upfront and we will confirm availability before you order. Ships free via LTL freight nationwide.
