DIN Fittingsby volzBased in Germany, Volz Group is a leading
manufacturer of stainless and carbon steel
DIN 2353 fittings. Brennan has entered into
a strategic alliance with Volz to bring these
high quality fittings to the North American
marketplace. Volz’s German manufacturing
standards, innovative plating technology and
wide DIN and Metric product range are now
available to you through Brennan.
For more information on DIN, Metric and other international fittings please contact a Brennan representative.
No compromise on qualityWe only use high quality stainless steel 1.4571 (316Ti) due to its exceptional
temperature and corrosion resistance. We recommend 316Ti for environments with
high salt levels, acidity, or near weld seams. The high service life of our tube and hose
fittings also reduces your replacement and maintenance costs.
High quality material for longer life• Exclusively V4A materials, 1.4571 (316Ti)
• Exceptional temperature and corrosion resistance
• Recommended for use with high salt levels or acids, or near weld seams
• 100% traceability to the smelting furnace
• Inspection certificate available upon request

Quality products in carbon steelOur carbon steel tube fittings offer excellent corrosion protection. The zinc-nickel
plating far exceeds US and international corrosion resistance standards, including
VDMA 24576 class K5. Our zinc-nickel plated fittings showed no traces of white or red
rust even after 1000 hours of exposure to salt spray testing.
Superior zinc-nickel plating• Exceptional rust resistance, over 1000 hours under salt spray testing
• High abrasion protection
• High temperature stability
• Good paintability
• Low contact corrosion with aluminum, even lower with stainless steel
• Clean, high quality appearance
carbon steel fittings and accessories
in the toughest conditionsWater, salt, acids, heat, impacts, vibrations, dirt, increasing amounts of corrosive
substances in the air – these are the environmental conditions which fittings are exposed
to. In shipbuilding, on drilling platforms, in wind turbines and hydropower plants, in railway
technology, construction machines, machine tools, and mobile hydraulics, our products last.
our zinc-nickel shinesThe surface makes a difference. Our zinc-nickel plating provides corrosion protection that
far exceeds US and international requirements, including class K5 VDMA standard 24576
for tube couplings. Our fittings withstand 1000 hours of salt spray tests without any trace
of white or red rust. This exceptional service life significantly lowers replacement and
maintenance costs. Plus, our plating offers not only premium corrosion protection but also
a premium appearance.
1,000 h
The solutionTo arrive at our plating solution we extensively evaluated both acid and alkaline zinc-
nickel coatings as well as alternative corrosion protection treatments, for example those
that dispense with the nickel components and base their protection on zinc only. In the
end, we selected a galvanic treatment with zinc-nickel in an acid environment, due to its
outstanding performance characteristics.
it’s in the detailsFirst of all, an approx. 8 μm thick base coating made of zinc with nickel content of 12 to
15% and a very homogeneous distribution of ZnNi molecules is applied galvanically. Then
an additional passivation with a coating thickness of approx. 500 nanometers is applied,
followed by the final coat: a 2 μm thick seal. These coats make the difference: they protect
the ZnNi surface and further enhance the corrosion resistance.
A conventional coating procedure, with an effciency near 40%, gives rise to embrittlement
in the carrier material. Our coating is applied with a significantly improved efficiency of
98%, minimizing hydrogen formation.

reliabilityOur products perform. Brennan DIN fittings by Volz protect your hydraulic systems, reducing
maintenance and preventing downtime.
Carbon steel or stainless steelYou have a choice: carbon steel or stainless steel. You get the best possible level of
performance and safety in both types of material.
Superior corrosion protectionThe long service life of our products reduces the total cost of ownership because longer life
means less maintenance. We achieve that by using high quality stainless steel (316Ti) and
by making our steel products extremely corrosion resistant with our superior zinc-nickel
coating. Our products are engineered for exceptional performance. Third party testing
certificates are available upon request.
brennan powerNot only are our fittings superior, but they are also backed by the power of Brennan’s
network of 11 distribution centers in North America with an additional 6000 independent
