DualPac® 2211
Pump Packing

Severe Slurry Packing

By inventing a new braiding process, Chesterton has successfully combined ePTFE
and aramid fibers in a unique configuration, thus allowing low-friction fibers to
seal the shaft and resilient fibers to provide strength and anti-extrusion benefits.
Combined in this way, DualPac 2211 provides all of the performance advantages
of ePTFE and aramid without the compromises of traditional mixed fibers packing.

412-W

Pump Packing
Multi-Service Packing
Chesterton 412-W combines a newly developed synthetic composite yarn with
a specially formulated break-in lubricant. Continuous filament center provides ten
times the tensile strength of typical packing fibers. Fibrous covering enables 412-W
to absorb twice the PTFE blocking agents of conventional packings. Chesterton
interbraid construction helps prevent migration of blocking agents so that 412-W
maintains density to inhibit wicking throughout its service life. 412-W also
incorporates a purified colloidal lubricant to prevent failure at start-up and
maintain continuous lubrication throughout the break-in process.

1727

Pump Packing
Multi-Lon™ Pump Packing
Chesterton’s 1727 Multi-Lon is a synthetic packing for general service pump
applications. Multi-Lon consists of interbraided, continuous, synthetic thermoset
fibers immunized with PTFE lubricant and a special silicone-free, break-in, sacrificial
lubricant. Unlike many synthetic yarns, it does not cause severe scoring. 1727 does
not cause electrolytic pitting like carbon or graphite yarns. It also does not have
the shaft speed limitations or the elongation/extrusion problems often associated
with PTFE fiber yarns.

Technical Data

1400R™

Valve Packing
Carbon-Reinforced Graphite Tape
Chesterton 1400R is a unique, reinforced, braided, graphite tape packing with
a corrosion inhibitor. The carbon yarn reinforcement is provided within the graphite
tape yarn as well as the braided construction. 1400R forms a homogeneous mass
under gland pressure, so that leakage is minimized in the packing set. The all-carbon/
graphite set withstands higher shaft speeds while limiting shaft/stem friction. The
structural carbon fiber reinforcement drastically lowers extrusion when 1400R
sets are installed in valves at higher pressures. In addition to its excellent sealing
capabilities in rotating equipment, 1400R is a superior valve sealing material. This
dual purpose design makes it a truly universal mechanical packing.

Advanced Materials and Construction

Chesterton 1600, 1601, and 1622 use advanced materials and construction to achieve
excellent sealing performance. Layers of graphite tape are formed into compact
strands; each strand is reinforced with an Inconel® wire mesh covering. This combats
extrusion without stem damage.
In Chesterton testing, valves packed with this advanced material were cycled 20,000
times leak-free without stem damage. These strands are square braided to form a
dense, but pliable, packing and a passive corrosion inhibitor is applied to resist stem
pitting. The final result is a packing that is flexible without being prone to extrusion
and able to seal reliably in extreme environments.

Control Valve Kits

Chesterton’s 1724 Low E Control Valve Kits are used on pneumatically actuated
control valves. 1724 Low E is best suited for services where the operating temperature
is a steady state with minimal thermal cycling and in applications where the
stem friction from pure graphite packing is too high for the valve’s actuator.
The kit contains all the parts necessary to repack the valve in the field with
Chesterton’s Live Loading system.
The kit includes a 1724 five-ring, die-formed PTFE packing set, a pre-cut carbon
spacer, pre-engineered Live Load assemblies, and new gland studs and nuts.
All packing rings and spacers are cut to allow installation without removal of the
valve actuator, simplifying the valve repacking procedure in the field. The Live Load

Valve Packing

Low E Isolation Valve Packing for Chemical Service

Chesterton 1726 Low E Packing minimizes isolation valve emissions to help
companies in the petrochemical, chemical, and oil and gas industries meet—and
even exceed—current emissions requirements. It is an innovative PTFE with
a carbon core stem packing that can accomplish these sealing levels without the
use of costly and time-consuming Live Loading assemblies.
1726 is uniquely constructed with a combination of PTFE surrounding a carbon
core in a true double-braided formation. The PTFE jacket provides chemical
resistance and lower friction while the specially formulated carbon core provides
superior sealing capability in harsh, corrosive environments. The result is a
non-hardening, flexible packing that is extremely strong yet extrusion-resistant,
resulting in a highly secure and reliable seal for emissions service. ■■ L ow E sealing performance

Sootblower Set
Chesterton 3000 Sootblower Sets are molded from an exclusive mixture containing
graphite and PTFE along with other materials. 3000 sets are designed with
a thicker than usual top ring to act as a bearing for the set and to resist extrusion.
All rings are split to go over the rod without being deformed. Exclusive Chesterton
formulation and processing allow rings to slip over rod and return to their molded
contour without cracking.
Sealing rings are designed so the top of each ring protects the ring above it. This
eliminates the majority of lip damage normally associated with early set failure.
Sealing ring lips expand inward and outward as increased gland pressure is applied.

5300 (GTPI) Die-Formed Inhibited Graphite Rings
Chesterton 5300 is a self-lubricating, low friction, high purity, precompressed,
die-formed ring manufactured from pure graphite ribbon tape without any
fillers, binders, or resins. Each ring is produced to an accurate specific density for
compression resistance, elasticity and retention of size and shape—all of which
are necessary to provide the best possible valve sealing performance.
5300 can withstand temperatures to 2760°C (5000°F) in a non-oxidizing atmosphere.
5300 incorporates an inorganic, passive inhibitor that reduces the corrosive
properties of graphite by producing a protective barrier between the packing and
the stem that will not degrade at high temperatures.

5150 Cartridge Valve Live Loading

The cartridge is a 5150 assembly outer container engineered for a valves’s specific
operating parameters. This results in the correct load being applied to the 5150
assembly based on cartridge height. The stainless steel cartridge makes installation
and maintenance easier.

5150 Live Loading Assembly

Stacked arrangements of uniquely designed disc springs automatically adjust
the gland to maintain constant, optimal sealing pressure on the packing set
during consolidation, or thermal cycling. Eliminates the need for frequent manual
adjustments, decreasing costly maintenance time and exposure/contamination
levels. The live load assembly is capable of storing many times the elastic energy
of standard gland bolts. Maintains optimal leakage control with minimal force,
making Live Loading especially valuable for motor operated or inaccessible valves.

5100 Split Carbon Sleeves

Independent testing confirmed by Chesterton Engineering clearly indicates that
a five-ring packing set produces optimum valve sealing. To effectively reduce
the number of rings in a stuffing box, the Chesterton system uses a precision
machined split carbon sleeve as a spacer in the bottom of the stuffing box. 5100
is manufactured from 99% pure graphite material which has a high compressive
strength and a low coefficient of expansion. Four inch lengths are available
to fit most stuffing boxes.
