SERTO
quick couplings – the Q5x series at a glance
SERTO’s three series of Q50, Q51 and Q52
provide a flexible range of quick couplings for industrial and hygienically
sensitive applications. Securely coded, contamination-free and particularly
compact, each series meets the strictest requirements in terms of ease of use,
leak tightness and reliability.
Separate
products for each application
Our quick couplings can be configured
flexibly. Choose from various sealant materials such as FFKM, EPDM and VMQ.
Other options are also available on request.
We also offer separate cleaning and
lubrication products, such as:
OX
SI
FC – food-safe lubricant under Regulation (EG) 1935/2004

technology / IT
Couplings
for energy & IT – compact, reliable and can be uncoupled dry
In the energy and IT tech sectors, liquid
coolant systems are essential for regulating the performance of frequency
inverters, transformers, network components and server hardware.
SERTO stainless steel couplings can provide
leakage-free connections in the tightest of spaces and are hard-wearing,
low-maintenance and exceptionally reliable over extended use.
Typical
applications
- Coolant systems for frequency inverters, power inverters and
rectifiers
- Temperature control and refrigeration devices
Market segment: pharma & biotech
Hygienic,
safe and straightforward: coupling solutions for biotech
In pharmaceutical and biotechnological
processes, media and temperature control circuits must be connected quickly,
securely and without any contamination.
SERTO quick couplings meet these requirements thanks to their one-handed operation,
clear mechanical and colour coding and smooth, easy-to-clean surfaces –
ideal for use in clean rooms and sensitive environments.
Typical
applications:
- Temperature control circuits in reactors, fermenters, mixers
- Media supply for storage tanks and filling systems
Semiconductors / Lasers
Clean, coded and precise: couplings for the high-tech sector
In semiconductor and laser technology, the
requirements for cleanliness, process reliability and repeatability are
extremely strict.
SERTO stainless steel couplings offer
leakage-free, lubricant-free and mechanically coded connections for ultrapure
water, gas or solvent circuits that are reliable even under clean room
conditions.
Typical
applications:
- Etching processes using hydrogen or acids
- Ultrapure water and solvent circuits (isopropanol)
- Temperature regulation with CO₂ lasers
- Inert gas circuits (e.g. argon)

Watch
now – new at SERTO: the TechTalk video series is launching!
In our TechTalks, we will be opening the
doors to our development department and giving you regular, exclusive insights
into new products, technological trends and innovative solutions from the world
of connection technology.
The first episode will deal with a topic
that is decisive in many applications: Quick couplings
Modular
& compatible: the SERTO modular system
SERTO quick couplings form part of a
well-designed modular system. A wide range of connections are available,
enabling the couplings to be incorporated easily and precisely into your
application:
- with internal or
external thread
- as bulkhead
connectors
- as threaded nipples
- or with hose nozzles
- more on request
Maximum flexibility – products from
different series can be used together.
