NEOLUBE Thread Sealant No.100

Low Halogen Content - High Chemical Purity

NEOLUBE Thread Sealant No.100

NEOLUBE NO. 100 is a high-performance, pipe thread sealant, designed for locking and sealing of metal pipes and fittings.

This sealant is a creamy paste formulated to impart lubricity for assembly purposes, to provide immediate low pressure sealing, and to cure to a solid for sealing and securing threaded pipe connections.

This product has excellent solvent resistance and withstands temperatures to 300°F (149°C) continuously.

NEOLUBE No. 100 does not contain Teflon.

Neolube No. 100 Is Not Normally Recommended For Use On Plastics (Particularly Thermoplastic Materials Where Stress Cracking Of The Plastic Could Result). Users Are Recommended To Confirm Compatibility With Such Substrates.

Neolube No. 100 Is Not Recommended For Use In Pure Oxygen And/or Oxygen Rich Systems And Should Not Be Selected As A Sealant For Chlorine Or Other Strong Oxidizing Materials. For Safe Handling Information On Neolube No. 100, Consult The Safety Data Sheet.

This pipe sealant contains no directly added Lead, Zinc, Mercury, Antimony, or Copper where such elements are leachable or could be released by breakdown of the sealant under expected environmental conditions.



1. Optimum results will be obtained on fittings that are clean. Clean all surfaces (external and internal) with reagent grade toluene, acetone, isopropyl alcohol or methyl ethyl ketone, and allow to dry.

2. Apply a 360° bead of NEOLUBE NO. 100 to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thoroughly fill the voids. For bigger threads and voids, adjust product amounts accordingly and apply a 360° bead of NEOLUBE NO. 100 on the female threads also.

3. Using accepted trade practices, assemble and wrench tighten fittings in accordance with manufacturer's recommendations.

4. Properly tightened fittings will seal instantly to moderate pressures. For maximum pressure resistance and solvent resistance, allow NEOLUBE NO. 100 to cure a minimum of 24 hours.

5. NEOLUBE NO. 100 has been formulated to cure without the use of heat or activators on stainless steel or other inactive surfaces. Higher temperatures will speed cure; lower temperatures will retard the cure process.

6. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.


Environmental Resistance

The following characteristics of NO. 100, PIPE THREAD SEALANT have been tested by an independent laboratory.

1. Calculated estimates under continued temperature and radiation exposure reported the following judgments:

  • "The product will provide a 40-year service life at ambient temperature not exceeding 122°F (50°C)."
  • "A 10-year performance life can be expected for service not exceeding 200°F (94°C)."
  • "The pipe thread sealant can be safely used to seal threaded pipe joints for approximately 1-year at a temperature of 250°F (131°C). Under high radiation and at temperatures greater than 250°F, long-term service life has not been predicted accurately."
  • Under non-nuclear (standard radiation) environments, thermal stability of this high purity PIPE THREAD SEALANT NO. 100 can be expected at temperatures up to 400°F.

2. Product is suitable for sealing low pressure steam, not exceeding 300°F (149°C).


4. Where aqueous washing systems are used to clean the surfaces before bonding, it is important to check for compatibility of the washing solution with the adhesive. In some cases these aqueous washes can affect the cure and performance of the adhesive.


Solvent Resistance

Suitable for use with piping systems containing air, water, gas, hydrocarbons (aromatics), boric acid, alcohols, halocarbons (perchlorethylene, trichlorethylene), organic acids (citric and acetic), mild mineral acids and bases (diluted and cold), and aqueous solutions of lithium salts, hydrazine and mercaptans.

Suitable Piping Materials

NEOLUBE NO. 100 is recommended for use on Iron, Magnesium, Bronze, Nickel, Zinc, Aluminum, Austenitic, Stainless Steel, Carbon Steel, Monel, Cadmium, bright plating, anodized surfaces, passivated surfaces and Titanium fittings. Elevated temperatures will cause threaded Copper to oxidize. High reliability Copper piping should be pickled prior to use of any sealant.

Fittings assembled with NEOLUBE NO. 100 may be disassembled with normal hand tools. Where hand tools do not work because of excessive engagement length or large diameters (over 1"), apply localized heat to approximately 250°C, and disassemble while hot. Cured product can be removed with a combination of soaking in a solvent and mechanical abrasion such as a wire brush.


NEOLUBE NO. 100 can be used in conjunction with all metals, glass, ceramics and many thermoset plastics such as phenolic, polyester, etc.

NEOLUBE NO. 100 will, however, soften and sometimes craze thermoplastics including: ABS, polycarbonate, vinyl, methacrylates, etc. They will also soften varnish and lacquer finishes. Most baked enamel finishes are not harmed by initial contact but should be wiped clean within an hour of application. The cured sealant will not affect any of these materials.


Store material in the original container. Maintain in a cool, dry location.

Optimal Storage: 8°C to 21°C (46°F to 70°F). Storage below 8°C (46°F) or greater than 28°C (82°F) can adversely affect product properties.
