Hydrogen leak Detection Tape
DetecTape™ is a chemochromic (color changing) selffusing silicone tape designed to detect hydrogen gas (H2) leaks in fuel cell, transmission, storage, and generation facilities. When in contact with concentrated hydrogen gas, the tape color changes from light gray to dark black in the event of a leak due to vibration or seal failure.

• No Adhesive - Bonds to itself on contact
• Can be used on all metal substrates
• Little to no surface preparation required
• Chemical and UV resistant
• Operating Temperature range: 0ºF up to +350ºF (-17ºC to +176ºC)
• Easy to install
• Changes color within minutes of detection
• Works with commonly used detection tools
