Tube, Pipe &
manufactures the Triple-Lok fitting (37° Flare), Ferulok
fitting (Flareless), Intru-lok fitting (Brass Flareless),
EO fitting (Metric Flareless), Seal-Lok fitting (O-ring Face
Seal), Pipe adapters and JIS fittings, making up the broadest
line of tube fittings in the industry. Manufactured with NPTF,
SAE straight threads, BSPP, BSPT, metric and flange ports.
U.S., Parker tube fittings are manufactured at their four
plants in western Ohio, stocked in .columbus, and are the
choice of OEM and MRO customers throughout the world.
Fittings Division forges its products from the best materials
available to assure strength and durability. For example,
tube nuts are "cold-formed" from quality materials
for close grained toughness. The result is a fitting with
total reliability - a fitting that can stand up to years of
forgings begins with solid metal extruded in round bars cut
to random lengths. The bars are then cut again into shorter
lengths (slugs), reheated to pliability and precisely pressed
between upper and lower die cavities at a pressure of approximately
25,000 pounds per square inch to form a forged blank. After
cooling, the flashing (extraneous metal pressed flat outside
the die cavity) is trimmed away and the forged blank is ready
under such extreme pressure produces two critical advantages
for Parker tube fittings:
- Extreme strength,
a result of a uniformly dense material
resistance to mechanical shock and vibration, due to an
uninterrupted gain flow along the contour of the fitting.
bar stock and forged shapes are machined by state-of-the-art
equipment into finished tube fittings that meet or exceed
global standards, such as SAE, MS and ISO.
machining operations are used to enhance the quality of Parker
tube fittings. For example, threads are manufactured from
a rolling process, providing greater strength, in addition
to a smoother surface that results in lower assembly friction.
fittings are zinc plated and then gold chromated on a new
state-of-the-art plating line providing corrosion protection
equal to or exceeding SAE and ISO standards. This process
is also more environmentally friendly than other plating methods.
Stainless steel fittings are passivated and aluminum fittings
are annodized or alodined.
process include: A dry-film torque-reducing coating for stainless
steel nuts and zinc phosphating, a corrosion resistant coating
for steel SAE flareless fittings.
