The easiest and safest method to join polyethylene piping

1
The easiest and safest method to join
polyethylene piping
2
Joint R D project with Consolidated Natural
Gas Mission Find a way to connect PE piping
that requires only one person, without the
use of expensive equipment 2 years in
development Extensive field testing and
evaluation with utility service personnel
3
Fast and easy installation, requires only
one person Total installed cost savings
versus electrofusion and heat-fusion joined
polyethylene No special tools or costly
installation equipment No special training
required to install Safe, dependable
performance for over 25 years

Non-corrosive couplings eliminate the need
for protective coatings and cathodic
protection Over 35 million couplings
installed Category 1 fitting Molded from
industry proven polyethylene Minimal stress
on PE tubing

25 years without a major design change
More than 35 million Permasert Couplings
now in service (more than 100 million
o-rings) The only PE mechanical fitting
approved and used at British Gas and Gaz
De France
Continuous life testing reveals no loss of
seal performance or degradation Liability
insurance Product flexibility
Multi-wall stiffeners Hundreds of
configurations Only major fitting with PE
as gas carrier

Permasert Couplings Use the ASTM D-2513
O.D. controlled pipe tube specification
Seals not affected by hoop stress Assemble
easily from lot to lot of pipe Do Not allow
installation of out of specification pipe
I.D. Seal Products Attempt to seal on the
uncontrolled I.D. surface Seal compression
affected by hoop stress Insertion force
varies widely by pipe wall thickness Do
allow installation of out of specification
pipe

Permasert Couplings Allow gas engineering
to set pipe quality limits Minimize the LDCs
liability exposure by providing instant
joint integrity feedback Provide an
objective second opinion for every
installation Are designed with the LDCs
interests in mind
I.D. Seal Products Allow the crew/contractor
to set pipe quality limits Maximize the LDCs
liability exposure by allowing
substandard installations Rely on
installers best guess regarding damage
assessment Are designed to overlook
performance altering anomalies

25 years, one design
Proven track record with more than 35
million Permaserts installed at virtually
every major utility in the U.S. and Canada
Molded from gas-grade polyethylene (identical
to the piping system) In-field quality control
built into every installation Ability to add
Permasert outlets to risers, valves, EFVs,
PMTTs, SFTTs, EFTTs and steel punch tees
Available with any wall size, any configuration
(1/2" CTS to 2" IPS) Faster, safer, more
reliable and more cost effective than any
other system
