NYLOG Blue
Part #RT201B, 30ml
Overview: Nylog Blue is viscoelastic liquid derived from synthetic refrigeration oil. Nonhardening, non-drying fluid which bonds tenaciously onto many different substrates. Nylog Blue
is completely miscible and compatible with virtually all refrigerants and base compressor oils.
The product will not cause any system restrictions, fouling or failure. NYLOG is used by OEM’s
and industry professionals worldwide.
Chemical Description: Proprietary viscoelastic Synthetic Lubricant. Slight petroleum odor and
color. Boiling point 450°F (232C) with de-polymerization occurring at 370°F (187C). Impervious
to water, however low level moisture absorption from prolong exposure to atmosphere can
occur. Please refer to SDS for more information.
Properties: Nylog Blue is a tacky and tenacious fluid. Modified petroleum compound and/or
derivative N.O.S.
Certifications: Mixtures of Nylog Blue with mineral, alkyl benzene, POE, PAG and PVE oils have
passed ASHRAE STD 97 seal tube compatibility testing with numerous refrigerants including R410a and R-32. NSF H2 registration number 119845. Kosher Certified by OK Kosher.
Storage and Handling: Do not use on Oxygen systems. Keep away from open flame. We only
recommend this product for use on air conditioning and refrigeration equipment. Use standard
precautionary measures when handling any chemical. Keep container closed and store away
from heat or direct sunlight. Use in well ventilated areas. Rinse any affect areas with soap and
water. Soak up spills with adsorbent material and dispose of as petroleum waste according to
Federal or State laws. KEEP OUT OF REACH OF CHILDREN.
Applications:
Flare Fittings: Both faces of the flare as well as the threaded connectors are coated. Primary
attention is given to the flare face. The majority of Nylog is pushed out of the flare boundary
but not completely expelled. Helium leak testing of flares treated in this manner were tighter
than flares coated with pipe dopes, resin adhesive, anaerobes, silicone or a dry connection.
Gaskets: The Nylog oil is absorbed into the gasket. Apply to both sides. Gaskets treated with
Nylog rarely dry or become heat fixed to the metal. The gaskets can be easily removed many
years later.
Tapered Pipe: Since pipe threads are never cut to the same tolerance; we recommend using
Nylog over and under Teflon tape for a superior high pressure seal.
Compression Fittings: The sealing method is similar to a flare connection but with less surface
area. Pre-coating the tubing, ferrule and threads with Nylog
Saddle Taps: Pre-clean the tubing with fine sandpaper to provide a clean surface. Coat the
gasket and tubing surface with Nylog. Assemble and apply sufficient torque.

O-Rings: Connections having a rubber or plastic ring gasket usually leak due to over-tightening.
The use of Nylog as an O-ring lubricant offers leak tight connections at low torques levels.
Excellent for Automotive A/C connections.
Assembly Lubricant: Nylog is a liquid lubricant. Typical uses include coating of pistons,
cylinders, rods, rings and valves. Refrigerant leakage is greatly reduced when shaft seals are
coated with Nylog. Coated Schrader valve cores do not leak and their depressors remain
lubricated. Pre-lubed solenoids, actuators, unloaders or ball valves are prevented from binding.
