Tourniquets

What These Are Built to Handle

Tourniquets are designed for one purpose: stopping uncontrolled arterial haemorrhage from the limbs when direct pressure is not sufficient or fast enough. They are used in traumatic injuries involving machinery, tools, vehicle accidents, firearms, penetrating trauma, and major falls — situations where blood loss can become fatal within minutes without immediate intervention.

In real-world application, tourniquets are applied early — often before a full casualty assessment is possible. The devices in this collection are selected to perform in exactly those conditions: one-handed self-application, reliable pressure retention during movement and evacuation, and consistent mechanical performance under stress.

These are not general first aid items. They are arterial bleeding control devices for serious trauma, and they should form part of a broader trauma management setup alongside haemostatic wound packing, pressure dressings, and airway management.

Who Uses These Tourniquets

CAT Gen 7 and SOF-T Wide tourniquets are the standard-issue devices across Australian defence, law enforcement, and emergency medical services. They are carried by paramedics, police, military and special operations personnel, fire and rescue teams, tactical medics, and remote area workers operating far from immediate medical care.

Beyond frontline professionals, tourniquets are increasingly carried by trained civilians — tradespeople working with machinery, 4WD and off-road travellers, farmers, construction workers, and anyone responsible for others in environments where rapid medical response isn't guaranteed.

If you operate with tools, machinery, vehicles, or in remote areas, a tourniquet is not optional equipment — it's the difference between a survivable injury and a preventable death.

What Matters When It Counts

Not all tourniquets perform the same under pressure. When choosing a tourniquet, reliability and usability matter more than brand recognition.

• One-handed application: You should be able to apply it to yourself if needed.
• Mechanical advantage: Windlass or ratcheting systems must generate and hold sufficient pressure.
• Durability: Materials should withstand heat, dirt, moisture, and repeated handling.
• Retention under movement: The tourniquet should not loosen during casualty movement.
• Training compatibility: It should match what you've been trained to use.

Avoid novelty designs or untested copies. In a real bleed, there's no margin for failure.

CAT Gen 7 Tourniquet — The Current Standard

The Combat Application Tourniquet Gen 7 is the most widely issued limb tourniquet by military and law enforcement globally. It features a self-adhering band, reinforced windlass system, and time-of-application window. The Gen 7 is approved for prehospital use and has a documented performance record in high-volume trauma environments. It is the baseline recommendation for anyone building a trauma kit who hasn't been trained on a specific alternative.

SOF-T Wide Tourniquet — For High-Mass Limbs

The SOF Tactical Tourniquet Wide is the preferred option for larger patients, high-mass limbs, and scenarios where maximum occlusion pressure is required. It uses a metal windlass and buckle system that maintains pressure across a wide range of limb sizes. The SOF-T Wide is standard issue across many Australian and international defence forces and is preferred by many clinicians for its consistent performance on large limbs.

SWAT-T Tourniquet — Versatile Stretch-and-Wrap Design

The SWAT-T (Stretch, Wrap and Tuck Tourniquet) is a stretch-applied device that can be used as a tourniquet, pressure dressing, or bandage. Its flexibility makes it suitable for irregular anatomical locations and paediatric use. It is often carried as a secondary device alongside a CAT or SOF-T.

Junctional Tourniquets — For Wounds at the Groin and Axilla

Standard limb tourniquets cannot be applied to wounds at junctional areas — the groin, axilla (armpit), and neck. Junctional tourniquets including the SAM Junctional Tourniquet are designed specifically for haemorrhage control in these locations. They are typically carried by tactical medics, military personnel, and advanced care providers as part of a full haemorrhage control capability.

Common Mistakes We See

One of the most common mistakes is carrying a tourniquet but never learning how to use it properly. Incorrect placement, insufficient tightening, or hesitation can all render it ineffective. Another issue is buying low-quality replicas that look the part but fail under load. Tourniquets are not the place to cut corners. We also see people storing tourniquets loose or buried at the bottom of a bag, making them difficult to access quickly. A tourniquet should be staged, accessible, and something you are confident deploying under stress — not just something you own.

A less common but serious mistake is purchasing counterfeit or replica tourniquets. Copies of the CAT Gen 7 and SOF-T Wide are widely available online at significantly lower prices. These devices replicate the appearance of the genuine article but frequently fail under the mechanical stress of actual application. TacMed supplies only genuine, TGA-compliant tourniquets from authorised Australian distributors.

Finally, tourniquet staging matters as much as tourniquet selection. A tourniquet stored in a sealed bag, buried in a kit, or not accessible with one hand is not a functioning tourniquet. Consider how and where yours is staged — within 10 seconds of access is the benchmark.

Questions We Get Asked

When should a tourniquet be used?

A tourniquet should be used for severe bleeding from an arm or leg that cannot be controlled with direct pressure, or when immediate bleeding control is required.

Are tourniquets safe to use?

When used correctly, modern tourniquets are safe and effective. The risk of uncontrolled bleeding far outweighs the risks associated with proper tourniquet use.

Can civilians legally carry tourniquets in Australia?

Yes. Tourniquets are legal to carry and are commonly included in first aid kits, trauma kits, and vehicle emergency setups.

What is the difference between a CAT Gen 7 and SOF-T Wide tourniquet?

Both are proven, widely issued devices. The CAT Gen 7 uses a self-adhering band and a plastic windlass — it is faster to apply and the most widely issued device globally. The SOF-T Wide uses a metal windlass and buckle system — it generates higher occlusion pressure and is preferred for high-mass limbs and larger patients. The right choice depends on your training, body type, and the environment you're operating in. If in doubt, the CAT Gen 7 is the standard starting point.

How tight should a tourniquet be?

A tourniquet must be tightened until bleeding stops. This will be uncomfortable, but inadequate tightening will not control bleeding.

Do tourniquets expire?

While many tourniquets do not have a strict expiry date, materials can degrade over time. Regular inspection and replacement when worn or damaged is recommended.

Should I carry more than one tourniquet?

In some scenarios, multiple tourniquets may be required. Many professionals carry at least two as part of their trauma setup.

Are the tourniquets sold by TacMed genuine?

Yes. TacMed supplies genuine, TGA-compliant tourniquets from authorised Australian distributors. Counterfeit copies of the CAT Gen 7 and SOF-T Wide are widely available online — these devices look identical but frequently fail under the mechanical stress of actual use. Every tourniquet on this page is the real product.

Do you stock tourniquet trainers?

Yes. Tourniquet trainers allow you to practise correct application technique without using a live device. Regular practice is essential — a tourniquet you've never practised with is significantly less effective in an emergency. See our training equipment collection for available options.
