Bostik Never-Seez NPBT-8 is a premium pipe and fitting lubricant and anti-seize compound formulated for maximum thread lubrication across a wide range of pipe threads and fittings. Enriched with PTFE (Teflon®) and other sealant-enhancing additives, this pipe compound with PTFE delivers greater thread engagement, more positive sealing, and reliable corrosion protection up to 525°F.
Bostik Never-Seez NPBT-8 is an industrial-grade anti-seize and thread lubricant compound. It is specifically designed to prevent corrosion, galling, and thread seizure on pipe fittings, making disassembly easier — even after prolonged exposure to high temperatures and high-pressure environments.
The inclusion of PTFE (Teflon®) distinguishes NPBT-8 from standard thread compounds by enhancing sealability and reducing the torque required during assembly and disassembly.
Bostik Never-Seez NPBT-8 is recommended for use on the following pipe materials:
It is compatible with fittings made from:
Standard thread sealants can fail under high pressure or extreme temperatures. A pipe compound with PTFE — like Bostik Never-Seez NPBT-8 — provides a more reliable seal by filling micro-gaps in thread surfaces and reducing friction during both assembly and disassembly. This minimizes the risk of leaks, thread damage, and costly maintenance downtime.
Q: What temperature can Bostik Never-Seez NPBT-8 withstand?
A: Bostik Never-Seez NPBT-8 is rated for use at temperatures up to 525°F (274°C), making it suitable for high-pressure steam and other high-heat pipe applications.
Q: Is NPBT-8 safe to use on stainless steel fittings?
A: Yes. Bostik Never-Seez NPBT-8 is compatible with stainless steel pipe and stainless steel fittings, and it actively prevents galling — a common problem when assembling stainless steel threaded connections.
Q: How does the PTFE in Never-Seez NPBT-8 improve performance?
A: The PTFE (Teflon®) additive in Never-Seez NPBT-8 enhances thread engagement and creates a more positive seal compared to standard pipe dope compounds. It also reduces friction, which lowers the torque required to tighten fittings and makes future disassembly significantly easier.
