Standard Specification for
“Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin)
Pipe Joints Using Flexible Elastomeric Seals1,2
This standard is issued under the fixed designation D 4161; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1.1 This specification covers axially unrestrained bell-and spigot gasket joints including couplings required for machine-made “fiberglass” (glass-fiber-reinforced thermosetting-resin)
pipe systems, 8 in. (200 mm) through 144 in. (3700 mm), using
flexible elastomeric seals to obtain soundness. The pipe systems may be pressure (typically up to 250 psi) or non pressure
systems for water or for chemicals or gases that are not
deleterious to the materials specified in this specification. This
specification covers materials, dimensions, test requirements,
and methods of testing.
1.2 The values stated in inch-pound units are to be regarded
as the standard. The values given in parentheses are provided
for information purposes only.

1.3 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
