Why Use Pipe Sealant?
Pipe sealants enhance sealing performance by providing:
- Leak-tight joints for metal threaded pipe connections
- High resistance to pressure, vibration, and temperature extremes
- Protection against rust, corrosion, and chemical exposure
- Strong gap-filling capability for worn or oversized threads
- Fast curing to reduce downtime
- Reliable performance in water, gas, oil, steam, and hydraulic systems
Where to Use Pipe Sealant
Pipe sealants are suitable for a wide range of fluid-handling and mechanical systems, including:
- Potable water lines and plumbing fixtures
- Gas lines, fuel systems, and diesel piping
- HVAC systems, water heaters, and pumps
- Hydraulic and pneumatic pipe connections
- High-pressure steam lines
- Stainless steel, galvanized, and large-diameter metal threads
- Industrial machinery and manufacturing equipment

Frequently Asked Questions (FAQ)
What is the best pipe sealant for gas lines?
High-viscosity anaerobic sealants like KP 77 provide secure sealing for gas, fuel, and oil systems.
Can pipe sealant be used on stainless steel?
Yes, anaerobic thread sealants cure effectively on stainless steel, especially with primer on passive metals.
What’s the difference between pipe sealant and pipe dope?
Pipe sealant chemically cures to form a permanent seal, while pipe dope remains soft and is less resistant to vibration and pressure.
Is pipe sealant safe for drinking water lines?
KP 77 is NSF-certified and approved for potable water applications.
Does pipe sealant work on PVC or plastic fittings?
Anaerobic sealants are for metal-to-metal threads only and should not be used on plastic.
What is the curing time?
Most formulas reach handling strength in 5–10 minutes and fully cure in approximately 12 hours.
