FAQs

1. What’s the difference between thread sealant and thread locker?

Thread sealant is designed to prevent leaks from threaded pipe joints by filling the space between threads, while thread locker secures threaded fasteners to prevent loosening due to vibration. Sealants are typically used on plumbing and gas fittings, whereas thread lockers are used in mechanical assemblies like engines or machinery. Using the wrong product can cause either leaks or seizing, so it’s crucial to choose based on whether you’re sealing fluids or securing bolts.

2. Can I use PTFE tape and thread sealant together?

While PTFE (Teflon) tape and liquid thread sealant both serve the same purpose—to prevent leaks—using both together is generally not recommended unless specified by the manufacturer. Combining them can cause excess material to squeeze into the system, potentially clogging valves or sensors. It’s best to use one or the other based on your application and preference for ease of use or durability.

3. Is thread sealant safe for drinking water systems?

Not all thread sealants are safe for potable water, so it’s essential to look for NSF or ANSI certifications indicating suitability for drinking water. Food-grade thread sealants are formulated without toxic chemicals and are safe for plumbing systems carrying drinking water. Always double-check product labels for “potable water approved” or equivalent phrases.

4. Why is my thread sealant still leaking after application?

Leaks after applying thread sealant usually occur due to incorrect application, insufficient curing time, or choosing the wrong type of sealant for the material or pressure rating. Always clean the threads thoroughly, apply sealant evenly, and allow it to cure per the manufacturer’s instructions. For high-pressure or gas systems, a specialized sealant rated for those conditions is essential.

5. Can thread sealants be used on plastic fittings?

Only specific thread sealants are safe for plastic threads, as many standard types contain solvents that can degrade plastic and cause cracks. Look for sealants explicitly labelled “plastic-compatible” or “PVC/CPVC approved.” Additionally, avoid over-tightening plastic fittings even with sealant, as this can strip the threads or stress the plastic.
