Product Description
NEOLUBE® No. 100 is a high-performance pipe thread sealant designed for locking and sealing metal pipes and fittings. It is a creamy paste formulated to impart lubricity for assembly, provide immediate low-pressure sealing, and cure to a solid for sealing and securing threaded pipe connections. It 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 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, consult the Safety Data Sheet.

This pipe sealant has 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.
Directions for Application
- Optimum results are obtained on clean fittings. Clean all surfaces (external and internal) with reagent-grade toluene, acetone, isopropyl alcohol, or methyl ethyl ketone, and allow to dry.
- 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 to the female threads as well.
- Using accepted trade practices, assemble and wrench-tighten fittings in accordance with manufacturer recommendations.
- Properly tightened fittings will seal instantly to moderate pressures. For maximum pressure and solvent resistance, allow NEOLUBE® No. 100 to cure a minimum of 24 hours.
- NEOLUBE® No. 100 is formulated to cure without heat or activators on stainless steel or other inactive surfaces. Higher temperatures speed cure; lower temperatures retard it.
- The product cures when confined in the absence of air between close-fitting metal surfaces, preventing loosening and leakage from shock and vibration.
Typical Performance of Cured Material
Environmental Resistance
The following characteristics have been tested by an independent laboratory. Calculated estimates under continued temperature and radiation exposure reported the following:
- The product will provide a 40-year service life at an 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 sealant can be safely used to seal threaded pipe joints for approximately 1 year at 250°F (131°C). Under high radiation and at temperatures above 250°F, long-term service life has not been predicted accurately.
- Under non-nuclear (standard radiation) environments, thermal stability can be expected at temperatures up to 400°F.
- Suitable for sealing low-pressure steam, not exceeding 300°F (149°C).
NEOLUBE® No. 100 is not recommended for sealing applications in reactor primary containment areas, where fitting operating temperatures exceed 300°F, or where the industrial standard requires welded assemblies. Where aqueous washing systems are used to clean surfaces before bonding, check compatibility of the washing solution with the adhesive, as some aqueous washes can affect cure and performance.
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
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.
Typical Properties of Cured Material
Physical Properties:
- Time to full strength on steel @ 72°F (25°C): 24 hours minimum
- Coefficient of thermal expansion (ISO 11359-2, K⁻¹): 0.10
- Coefficient of thermal conductivity (ISO 8302, W/(m·K)): 0.10
- Specific heat, kJ/(kg·K): 0.30
Adhesive Properties (Breakaway Torque, ISO 10964; 3/8 x 24 steel nuts & bolts, grade 2):
- After 24 hours @ 25°C: 0.9 N·m (8 lb·in)
- Cured 24 hours @ 93°C, tested @ 25°C: 2.3 N·m (20 lb·in)
Disassembly
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 solvent soaking and mechanical abrasion such as a wire brush.
Material Compatibility
NEOLUBE® No. 100 can be used with many metals, glass, ceramics, and some thermoset plastics such as phenolic and polyester. It will, however, soften and sometimes craze thermoplastics including ABS, polycarbonate, vinyl, and methacrylates, and will 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.
Storage Conditions
Store material in the original container in a cool, dry location. Optimal storage: 8°C to 21°C (46°F to 70°F). Storage below 8°C (46°F) or above 28°C (82°F) can adversely affect product properties.
Material removed from containers may be contaminated during use; do not return product to original containers. NEOLUBE® No. 100 has a shelf life of 24 months from the date outlined on the Certificate of Quality Conformance. Refer to the Certificate of Quality Conformance for the expiration date.
