The B-Safe Ball Valve Lockout is made of strong "Polypropylene" plastic. It is fully dielectric and highly resistant to solvents and other chemical products. It is also highly resistant to cracking, abrasion and extreme temperature changes, -50°F (-46°C) to 360° F (183°C). For valves from 3/8" to 1-1/4".

Features:

• An easy way to prevent accidental energization of quarter-turn ball valves
• Safe, efficient and inexpensive protection-installs in seconds
• Fully dielectric (nonconducting) polypropylene plastic
• Highly resistant to solvents and other chemical products
• Highly resistant to cracking and abrasion
• Can lock valves in the closed or open position (where applicable)
• Resistant to extreme temperature changes
