Date: 12/08/25

Whether you’re building a system from scratch, modifying pipework to accommodate new equipment, undertaking regular maintenance or doing urgent repairs, you not only need your pipe seals to be strong and watertight, you need them to be compliant too. 

369 self-fusing pipe sealant tape from SleeveIt is designed to be as strong legally as it is practically, giving you complete confidence and compliance whatever the job.

Measurable strength

At SleeveIt, we don’t just claim our pipe sealant tape is strong, we prove it with independent laboratory assessments. As you’ll see on our data sheet, 369 pipe sealant tape delivers on so many different metrics, including:

• Tensile strength of 700psi minimum

• Elongation ability of 300% minimum

• Tear strength of 600ppi minimum

• Hardness of 40 ± 10 Shore A

This is why we rate our pipe sealant tape to be excellent for so many properties, including moisture resistance, UV resistance, electrical insulation, ozone resistance and corrosion prevention. It also rates good for solvent resistance, flame resistance, abrasion resistance and tear resistance. 369 pipe sealant tape also demonstrates excellent temperature tolerance, remaining stable at 180°C and withstanding short term exposure up to 260°C.

Exceeding industry standards

We’re confident that our pipe sealant tape will provide you with a performance above and beyond what you need, wherever you need it. But don’t take our word for it; check out the full range of industry standards and regulatory compliance our pipe sealant tape achieves:
