Right Thread Configuration Before It Ships

Right Thread Configuration Before It Ships

The vendor who ships a male-thread holder when your hose requires female threading doesn't just cost you time — they halt your water shuttle operation mid-incident. That is the enemy: a supply line holder that arrives with the wrong thread configuration and leaves your crew improvising on the fireground. At Tank Vault, we confirm your thread orientation and type by email after every purchase. NST, NPT, BSP, or CAM — male or female — we verify the exact spec before the holder ships to your station. No guessing, no returns, no downtime.

Four Sizes Cover Your Entire Hose Inventory

Four Sizes Cover Your Entire Hose Inventory

Water shuttle operations don't run one hose diameter. Your deployment might require 2.5-inch supply lines on one call and 5-inch on the next. The FDT Single Supply Line Holder comes in four sizes — 2.5-inch, 3-inch, 4-inch, and 5-inch — so you can match the holder to your existing hose inventory without adapter fittings that create failure points. Each holder mounts directly to any Fol-Da-Tank frame, adding industrial-grade stability that keeps your supply line locked in position during high-flow fill operations. Select the size that matches your current setup, and we handle the thread confirmation from there.

Female Coupler Standard for Direct Hose Connection

Female Coupler Standard for Direct Hose Connection

A female supply line coupler is the most common field configuration — and for good reason. The inside threading on a female holder accepts the outside threading on your fire hose, creating a direct, secure connection without additional adapters. This is the setup most fire departments and municipal water operations already run, which means less troubleshooting on arrival and faster deployment when minutes matter. If your operation requires a male orientation instead, we confirm that by email after purchase. Either way, the holder arrives spec'd for your exact coupling setup, not a guess at what might work.

Compatibility Check

Confirm these conditions before ordering

  • Mounted to a Fol-Da-Tank frame tank
  • Supply line diameter matches 2.5", 3", 4", or 5" holder size

★★★★★
“We run 3-inch supply lines on all our Fol-Da-Tanks and needed holders that wouldn't back off under flow. Tank Vault confirmed our NST female thread by email before shipping — holder showed up, bolted right to the frame, and locked the line solid. No phone tag, no wrong threads.”

Frequently Asked Questions

Check your existing fire hose couplings. NST (National Standard Thread) is the most common in US fire service. NPT is used for pipe-thread connections. BSP is standard in international fittings. CAM locks are quick-connect fittings common in water transfer operations. If you are unsure, check the threading on your current supply line or consult your apparatus specifications. After purchase, Tank Vault confirms your thread type and orientation by email before the holder ships — so even if you are uncertain at checkout, we verify the correct configuration with you directly.
This supply line holder is designed specifically for Fol-Da-Tank frame tanks. We cannot guarantee fitment on third-party or custom frames. If your operation uses a different portable tank brand, contact us before ordering with your frame specifications and we can advise whether this holder will work or recommend an alternative that matches your setup.
Lead times vary based on the size and thread configuration you select. After purchase, we confirm your specifications by email, and the holder ships once your configuration is verified. If you have a specific deadline — a training date, deployment window, or compliance inspection — contact us before ordering and we will confirm whether we can meet your timeline.
That is exactly why we confirm your thread type and orientation by email after purchase. We verify NST, NPT, BSP, or CAM threading and male or female orientation before the holder leaves our system. If the confirmed specification still does not match your setup on arrival, contact us immediately — our 30-day return policy covers uninstalled items in original packaging, and we will resolve the mismatch without a runaround.
This supply line holder is a structural accessory for Fol-Da-Tank frame tanks and does not carry a standalone UL listing. UL certification applies to fuel storage tanks and containment systems in our catalog. For this holder, the relevant quality standard is Fol-Da-Tank's own manufacturing specifications, which we verify through our authorized dealer relationship. If you need documentation for your apparatus or station records, contact us and we will provide what is available from the manufacturer.
Yes. Orders over $500 qualify for financing through Affirm, with monthly payments as low as $52. Select Affirm at checkout to see your exact payment terms. Klarna is also available with four interest-free installments. If your department or municipality requires a purchase order or net-30 terms, contact us — we support PO-based ordering for industrial and government buyers.
