ThreeBond Pipe Sealants: Ensuring Leak‑Proof, Durable Piping Systems
Piping networks form the unseen arteries of modern buildings and industrial facilities, delivering water, gas, air, and many other essential fluids. Yet even the most robust pipes can fail at their threaded connections if not sealed properly. That’s where liquid pipe sealants come in—filling microscopic gaps in threads, preventing leaks, dampening vibration, and offering chemical and temperature resistance. In this comprehensive guide, we explore the full ThreeBond range of pipe sealants, from general‑purpose thread gaskets to specialty formulations for LPG, natural gas, steel‑lined water pipes, and PE gas piping. Whether you’re an MEP engineer, maintenance manager, or procurement specialist, you’ll find the right ThreeBond solution to keep your piping systems safe, efficient, and long‑lasting.
Why Choose Liquid Pipe Sealants?
Traditional paper or gasket‑style seals can be cumbersome to install, may shift under vibration, and often require precise cutting to size. Liquid sealants, by contrast:
- Conform to any thread size: Brush, roll, or apply directly to male or female threads.
- Fill microscopic clearances: Achieve reliable sealing even on worn or mismatched fittings.
- Vibration & Impact Resistance: Remain flexible under pounding or movement.
- Chemical & Temperature Resistance: Form resilient gaskets that withstand gases, oils, and hot or cold water.
- Easy Maintenance: Disassemble fittings when needed without damaging threads.
With these advantages, ThreeBond’s liquid sealants simplify installation, reduce downtime, and prevent costly leaks.
ThreeBond 1110F / 1110G: Anaerobic Liquid Gasket for Metal Pipes
Key Features
- Anaerobic cure: cures only in the absence of air, i.e., inside the metal threads.
- Excellent lubricity reduces galling during tightening.
- Permits disassembly when required.
Applications
- Sealing and anti‑loosening on metal threaded joints for cold/hot water, oil, air, and drain pipes.
- Note: Not for use on potable hot water supply lines.
Why It Matters
Anaerobic gaskets like 1110F/G form a tough, thread‑locking film that prevents leaks and loosening under vibration. Their lubricating action also protects metal threads during assembly.
ThreeBond 4221 / 4221B / 4230: Corrosion‑Resistant Sealant for Lined Steel Water Pipes
Key Features
- Liquid sealant formulated for steel pipes lined with epoxy or plastic.
- Anticorrosive properties protect metal surfaces wherever the liner ends.
- Meets JWWA K 161 standards for water supply applications.
Applications
- Sealing end faces and threaded joints on lined steel piping (up to 80A).
- Ideal for water treatment plants, boiler feed lines, and hot water supply systems.
Why It Matters
Where epoxy‑lined steel pipes end, bare metal is vulnerable to corrosion. ThreeBond’s anticorrosive sealants guard these critical junctions, extending the service life of municipal and industrial water networks.
ThreeBond 4320B: Semi‑Dry Sealant for LPG, CNG, PNG
Key Features
- Semi‑dry formulation: eliminates messy squeeze‑out.
- Excellent vibration and impact resistance.
- Special grade for LPG, CNG, and other pressurized gases.
Applications
- Threaded joints on city‑gas piping (15A–80A).
- Municipal LPG, CNG, and PNG distribution systems.
Why It Matters
When sealing high‑pressure gas lines, you need a sealant that won’t slump or drip, yet fills every thread. ThreeBond 4320B’s semi‑dry formula stays put under vibration and ensures long‑term safety in gas piping networks.
ThreeBond 4332C: Silicone Gas Piping Sealant
Key Features
- RTV silicone base: remains elastic across temperature swings.
- Non‑sagging, easy to apply with fine control.
- Compatible with natural gas, city gas, propane, and LPG.
Applications
- Thread sealing on gas piping for residential, commercial, and industrial use.
Why It Matters
Silicone’s flexibility and wide temperature range make 4332C an excellent choice for above‑ground or exposed piping. It stays elastic in winter cold and summer heat, maintaining a leak‑proof barrier.
ThreeBond 6701D / 6702: Industrial Wet Wipers for PE Gas Piping
Key Feat ures
- Rapid‑drying cleaning agents that leave no residue.
- Specially designed wet wipes (6701D pouch, 6702 tub) for on‑site use.
Applications
- Cleaning welded joints and fittings on polyethylene (PE) gas piping prior to sealing.
Why It Matters
Proper adhesion on PE gas pipes demands immaculate cleanliness. ThreeBond’s wet wipers remove oils, dirt, and oxidation, ensuring that subsequent sealants bond perfectly.
Best Practices for Pipe Sealant Application
- Surface Preparation
- For metal threads: Brush or wipe with an appropriate cleaner (e.g., ThreeBond 6701D) to remove oil and debris.
- For gas piping: Ensure the interior surfaces are free from welding slag or plastic residue.
- Sealant Selection
- Gas piping: 4320B for high‑pressure LPG/CNG; 4332C for flexible silicone sealing.
- General metal piping: 1110F/G for anaerobic gasketing; 4221/4221B for water lines.
- Application Technique
- Apply sealant evenly around male threads, covering the first 2–3 turns.
- Assemble fittings by hand, then tighten per torque specifications. Excess sealant will fill gaps without over‑squeezing.
- Curing & Testing
- Allow anaerobic sealants (1110F/G) to cure (typically 20–30 minutes).
- Pressure‑test gas lines per regulatory standards before commissioning.
By following these steps, you’ll achieve leak‑tight, durable piping connections every time.
