Company
For more than 50 years now, the STAUFF Group has been
developing, manufacturing and distributing pipework equipment
and hydraulic components for mechanical and plant engineering as
well as for service and industrial maintenance. The overall product
range currently includes about 33,000 standard products as well
as numerous special and system solutions according to customer
requirements or based on own developments.
All STAUFF products undergo relevant testing in accordance with
international regulations and are governed by the high standards
of the in-house quality management system. Furthermore, many
items have received certifications and approvals from various
international institutes, organisations and authorities who have
independently confirmed the quality and performance of the
products.
Wholly-owned manufacturing, sales and service facilities in
18 countries and a tight network of authorised distributors and
representatives in all major industrial regions of the world ensure
high presence and service paired with a maximum of availability.
The STAUFF Connect portfolio is closely aligned with the market
requirements and contains an extensive range of tube connectors
made of carbon steel for metric tubes with outer diameters
ranging from 4 to 42 mm in accordance with ISO 8434-1 /
DIN 2353:
24° cutting ring fittings
24° taper fittings with O-ring
24° weld cones with O-ring
37° flared tube fittings
The product range is completed by check and alternating valves for
inline installation, thread reducers as well as blanking plugs and
screws.

Special product types and sizes as well as alternative materials,
material combinations and surface coatings deviating from the
standards can be realised on request.
Automated assembly machinery and hardened, wear-resistant
tools enable the reliable assembly of tube connectors – both for
series production in the workshop and on-site.
Because of its versatility and flexibility, the patented STAUFF Form
Tube Forming System is undoubtedly the best solution for series
production, in particular for applications with highest requirements
with regards to safety, reliability and repeatability as well as
process stability.

24° tube fittings and accessories made from carbon steel of the STAUFF Connect range complement the extensive range of original
STAUFF components for fluid power applications from own development and production. Experience outstanding product quality and
increased operational safety and reliability for your equipment. Benefit from the advantages of single-sourcing all hydraulic pipework
components from the manufacturer.
Characteristics
Users across all industries and applications benefit from
sophisticated technology, which has been developed for and
used by the very demanding automotive industry for many years
now and that is already the proven standard for a large proportion
or STAUFF components in other product groups since 2007.
More than 1,200 hours resistance to red rust /
base metal corrosion
White rust occurs only by way of a slight grey haze
Easily surpassing the requirements of the corrosion protection
class K5 as defined by the VDMA, the German Engineering
Association (360 hours resistance to white rust / 720 hours
resistance to red rust)
Free of hexavalent chrome Cr(VI)
ELV compliant according to 2000/53/EC
(End of Life Vehicles Directive)
REACH compliant according to 1907/2006/EC (Registration,
Evaluation, Authorisation and Restriction of Chemicals)
RoHS compliant according to 2002/95/EC
(Restrictions of the Use of Hazardous Substances)
Appealing colour scheme with a bright semi-gloss
surface finish – comparable to Stainless Steel
Significantly reduced tendency to corrosion by contact with
other metals (such as Aluminium and Stainless Steel)
Improved abrasion resistance due to the ductility /
plastic deformability of the coating
Little to no risk of triggering allergies – nickel release is down
to only a fraction of the statutory limits relating to objects
which come into direct and prolonged contact with the skin
Good paint adhesion properties and resistance against
all commonly used hydraulic media
Zinc/Nickel Coating
With more than 1,200 hours resistance against red rust, the
Zinc/Nickel coating, which is used for the entire STAUFF Connect
range, offers excellent surface protection far beyond the previous
market standards – even after transport, handling and assembly.
This was successfully confirmed by testing in the salt-spray
chamber according to DIN EN ISO 9227.

Cutting Ring
The operating principle of the metallic sealing cutting ring, which
is constantly used both in the Light and the Heavy Series, is
based on two cutting edges. Thanks to the optimised geometry of
the ring, the two edges do not cut simultaneously, but rather one
after the other, thus increasing the incising effect. In addition to
ensuring the necessary force and form closure in the cutting area,
this method also maximises the tear strength of the fitting.

Pressure Resistance
Due to the careful selection and processing of high-strength
materials, the pressure resistance of tube connectors of the
STAUFF Connect range clearly exceeds the requirements of the
ISO 8434-1 and DIN 2353 standards: For selected types and
sizes, original STAUFF parts can be used in applications with
nominal pressures up to 800 bar in the Heavy Series and up to
500 bar in the Light Series.
The first cutting edge guarantees a firm seat for the ring and the
secure holding of the tube. A clearly visible material raise in front
of the first cutting edge indicates to tube fitters and inspectors
that the assembly has been successfully completed. The second
edge supports the overall function.
Due to the optimised design of the cutting ring in the central
region as well as in the shoulder area, a larger tube support
surface with a high surface pressure is achieved without jamming
the cutting ring. This ensures uniform distribution of force. The
outer support surfaces of the cutting ring are smoothed, thus
minimising friction losses during the assembly.
This pressure range increase does not only mean additional
operational safety and reliability, but also enhanced efficiency and
cost-effectiveness: Significantly smaller tube connectors of the
Light Series can be used instead of the Heavy Series while fully
maintaining the standard dimensions, and thus reducing weight,
mounting space and assembly forces.
Unless otherwise stated, all parts have been designed with a
four-fold safety on the nominal pressure, which means that burst
pressures during static load tests must be at least four times
higher than the nominal pressures.
