PRODUCT DESCRIPTION
LOCTITE
®
55™ provides the following product characteristics:
Technology Coated multifilament thread
Chemical Type Polyamide thread with inert
proprietary paste
Appearance White colored, coated cord
LMS
Cure Not applicable
Application Thread sealing
LOCTITE
®
55™ is a general purpose, threaded pipe and fitting
sealant which is wound from the dispensing package onto the
threads of the pipe. It is supplied in containers, which serve for
both storage and dispensing purposes. Recommended for
sealing metal and plastic tapered pipe threads and fittings up
to 4" NPT (National Pipe Thread) for use in industrial
applications in aqueous and non-aqueous fluids. Particularly
suitable in threaded assembly applications that require
immediate use and may undergo small readjustments before
use. This product is typically used in applications up to 149 °C.
UL Classification
Classified by Underwriters Laboratories Inc.

for use on
threaded joints of metal pipes not exceeding 1-1/2 inch pipe
size in devices handling gasoline, petroleum oils and not
exceeding 1 inch pipe size in devices handling natural gas
(pressures not over 2.07 MPa), propane and butane.
NSF International
Certified to ANSI/NSF Standard 61 for use in commercial and
residential potable water systems not exceeding 82° C.

Pressure Resistance
LOCTITE
®
55™ was successfully tested for pressure
resistance and sealability to 69 MPa. 3/8 NPT steel pipe tees
and plugs were assembled and pre-torqued to 27 N·m prior to
testing at 69 MPa hydraulic pressure @ 23 °C according to
ASTM D 1599.
TYPICAL ENVIRONMENTAL RESISTANCE
LOCTITE
®
55™ has resistance to most common industrial
fluids and gasses.
Steam Compatibility
LOCTITE
®
55™ was successfully tested for steam compatiblity
to 0.17 MPa. 1.5 " NPT were assembled and tested at 0.17
MPa pressure @ 130 °C for 1,000 hours.
