HOSE
ASSEMBLIES
SZR SYSTEM (Without retention zone) and 3A Hose Assemblies
The concept of SZR* has been fully researched for the flexible hoses produced by VENAIR. This system ensures that the hoses equipped
with metal fittings on both ends satisfy even the most demanding requirements of the food, pharmaceutical, cosmetics and chemical
market, since all areas where contamination may occur between the joint of the hose and the fittings are eliminated by placing them at
the same level.
The SZR* system is designed to prevent the utmost differences in diameter between the metal fitting and the hose, ensuring continuous
product flow without inner turbulence. This leads to time saving by allowing on-site cleaning (CIP) to be performed without disassembly.
The SZR assembly system ensures a higher level of non-retention in the flexible hoses, as well as greater safety of use. Moreover, our
crimped hoses can be Certified according to the 3A Sanitary Standard 62-02 for hose assemblies.
Quality of finish
The roughness of the inner surface of the SZR* fittings presents a maximum rugosity of 0.8 microns and can be improved on request. The
batch number for the raw material used is indicated on each fitting. All connections are manufactured in a single block, without welds,
and the flexed 45º or 90º connections are secured by an orbital weld.

VENAIR SILICONE ASSEMBLIES IN ACCORDANCE WITH 3-A SSI # 62-02
3-A Sanitary Standards, Inc. (3-A SSI) is an independent, not-for-profit corporation dedicated to advancing hygienic equipment
design for the food, beverage, and pharmaceutical industries. 3-A SSI represents the interests of three stakeholder groups
with a common commitment to promoting food safety and the public health-regulatory sanitarians, equipment fabricators and
processors.
3-A Sanitary Standard for Hose Assemblies (Number 62-02) is a standard which covers the sanitary aspects of the hose assem-
blies consisting of a sanitary couplings permanently attached to one of both ends of multiple-use smooth-bore hoses in a man-
ner such that the resultant hose-to-coupling junction is suitable for cleaning-in-place or ‘CIPable’. 3-A SSI formulates sanitary
standards and accepted practices for the sanitary design, fabrication, installation and cleanability of dairy and food equipment
or systems used to handle, process and package consumable products where a high degree of sanitation is required.
Venair’s dedication in providing the highest possible quality, sanitary and hygienic hose assemblies has driven us to obtain and
uphold the standards and requirements outlined by the 3-A association and in regards the hose assemblies we manufacture. Just
another step towards our management driven objective: Offer our customers the highest quality products in the market.
