FAQ

What is a thread sealer?
A thread sealer is a compound applied to threaded fittings and fasteners to prevent leaks of fluids or gases at the joint. It fills minor gaps and acts as a barrier to air, oil, fuel, coolant, or hydraulic fluids.

Where should I use thread sealer?
Thread sealers are ideal for fuel and coolant fittings, oil pressure sensors, coolant temperature senders, brake and hydraulic lines, pipe threads, and plumbing connections—anywhere a leak-proof seal is critical.

What types of thread sealers do you offer?
We carry brush-on pastes, tapes (PTFE), anaerobic liquid sealers, and specialty formulas designed for high pressure, fuel-safe, or high-temperature applications.

Are thread sealers removable?
Yes! Most thread sealers remain soft or semi-flexible for future removal, while still creating a strong, leak-resistant seal. Some anaerobic types require basic tools for disassembly once cured.

Are thread sealers safe with metals and plastics?
Absolutely. Our thread sealers are compatible with most automotive metals and plastics—always check product instructions for material-specific recommendations.

Will thread sealer harden or crack over time?
Quality thread sealers are formulated to resist cracking, shrinking, or hardening, even after years of heat, pressure, and vibration.

How do I apply thread sealer?
Clean the threads, then apply a thin, even coat to the male threads before assembly. Tighten as usual and wipe away any excess. Always follow product instructions for best results.

What if my sealer arrives dried out, leaking, or unusable?
Customer satisfaction is our priority. If you receive a damaged or unusable product, contact us within 7 days for a replacement, exchange, or refund.
