Total Cylinder Protection
The Gas Cylinder Lockout Device brings effortless safety to every workspace by sealing off valve access in a matter of seconds. Designed to shield both personnel and equipment, it offers peace of mind whether you’re in a busy workshop, warehouse or laboratory.
Built for simplicity and reliability, this lockout equipment streamlines your maintenance routines and minimises downtime. Its robust construction and intuitive design ensure that once it’s in place, the risk of accidental or unauthorised operation is eliminated.
Quick Clip-On
With its simple clip-shut mechanism, this device secures around the valve head in under five seconds, allowing teams to focus on the task at hand rather than fussing over tools. Installation requires no specialist training or additional hardware, so you can lock out cylinders immediately wherever they’re needed.
Removal is just as swift, meaning you can transition from maintenance to operation without unnecessary delay. The ease of use keeps workflows moving smoothly and reduces the chance of human error during critical lockout procedures.


Interlocking Panels
Two precision-engineered panels embrace the valve head, creating a seamless barrier that cannot be slipped or prised open. This sturdy dual-lock plate design ensures the valve remains completely inaccessible until all authorised padlocks are removed.
The panels’ robust fit also guards against accidental impacts and vibrations, so the device stays firmly in place even in high-traffic or heavy-duty environments. Teams can trust that once it’s attached, the valve is fully isolated until they decide otherwise.

Broad Cylinder Fit
Engineered to accommodate neck rings up to 35 mm in diameter, this lockout equipment works with the vast majority of standard gas cylinders without requiring adapters. One versatile device covers all your cylinder types, cutting down on inventory and simplifying safety checks.
Whether you’re switching between cylinder brands or moving across different departments, you won’t need a different lockout for each size. That universal compatibility makes it the go-to safety solution for mixed-use facilities.


Multi-User Security
Its design incorporates three padlock holes (8 mm diameter), enabling multiple team members or departments to secure the valve simultaneously with their own keys. Shifts can add or remove their lock without disturbing others, streamlining handovers during extended maintenance.
This layered approach discourages unauthorised access by ensuring no single person can override the isolation alone. It promotes shared responsibility and bolsters accountability throughout every stage of your lockout procedures.
Tough Polypropylene
The device is crafted from impact-resistant, heat-resistant polypropylene that withstands knocks, drops and extreme temperatures without cracking or warping. Its insulating properties also protect against thermal stress, maintaining a snug fit around the valve head.
By enduring harsh conditions and chemical exposure, the lockout equipment delivers consistent performance across countless maintenance cycles. That long-term reliability minimises replacement costs and downtime in busy industrial environments.


Clear Safety Label
A prominently moulded message reading “DANGER locked out, do not remove, property of ___” provides immediate clarity on lockout status. The imprint remains crisp and legible even after prolonged exposure to sunlight, cleaning agents and wear.
The integrated fill-in space lets teams add names or department details, deterring tampering and making ownership instantly visible. This transparency speeds up safety audits and ensures everyone knows who applied the lockout.
Bright Yellow Finish
The vivid yellow housing ensures locked-out cylinders stand out in busy or dimly lit areas, catching attention at a glance. Its high-visibility hue alerts staff immediately to isolation points, reducing the risk of accidental valve operation.
By contrasting sharply with machinery and storage racks, the device enhances situational awareness across your workspace. That extra pop of colour helps teams spot locked cylinders quickly, keeping operations safe and efficient.
