Gruvlok® couplings and fittings are used for joining grooved end steel, stainless
steel and ductile iron pipe as well as copper tube in a variety of applications.
The couplings provide a self-restraining joint for service conditions that range
from vacuum to high pressure and temperatures ranging from -40 - 350 degrees F
(-40 - 177 degrees C). Standard couplings can handle pipe diameter sizes ranging
from 1" - 24" (25.4 - 610 mm), and custom sizes are also available.
The Gruvlok system consists of grooved couplings and fittings, branch outlet
connections, plain end connections, butterfly valves, check valves, suction
diffusers,
tee strainers, gaskets, and grooving machines. EPDM “C” style gaskets
are NSF-61, Section 8, certified to potable water use and bear the NSF certification
mark. A variety of gasket styles and elastomer compounds are available to meet
individual application needs. Contact manufacturer for the latest UL/ULC listed
and FM approved pressure ratings versus pipe schedule.
Gruvlok Advanced Copper Method Couplings are available in sizes from 2" -
8" (51 - 203 mm) and provide a rigid connection, on copper piping systems.
The couplings come with EPDM “C” style gaskets as the standard offering.
These fittings are wrot per ASTM B75 and ANSI B16.22 alloy C12200 copper.
Gruvlok Stainless Steel Method Couplings are available in sizes from 1 1/4"
- 8" (32 - 203 mm) and are made of cast stainless steel per ASTM A743 CF8M,
which is ideal for corrosive environments. Any Gruvlok gasket material may be
used in the couplings, allowing a broad array of applications. Gruvlok Stainless
Steel Method offers a complete line of flow control valves as well as fabricated
(304 Series Stainless) and cast (CF8M) stainless steel fittings from 1 1/4"
- 8" (32 - 203 mm) in size.
The Gruvlok AWWA Piping System is ideal for joining grooved end ductile piping,
grooved in accordance with ANSI/AWWA C606. Products consist of a full selection
of couplings, flanges and fittings in 3" - 24" (76 - 610 mm) sizes with
operating pressures as high as 500 psig. The Figure 7901 AWWA coupling housings,
flanges and fittings are cast ductile iron per ASTM A536. The wall thickness of
the fittings complies with ANSI/AWWA C153 or C110 standards.
Gruvlok couplings styles are available in rigid connections as well as flexible
designs, which allow for pipe expansion and contraction due to temperature changes,
minimizing or eliminating the need for expansion joints. Gruvlok couplings disassemble
easily. The resilient elastomeric gasket and pre-designed gap of the Gruvlok coupling
help isolate and absorb flow noise and vibration transmission. The couplings engage
the pipe around the entire circumference and restrain pipe ends from separation
due to pressure and other forces. Gruvlok couplings absorb and eliminate stresses
from seismic tremors or settlement of buried pipe.
