LONG LIFE EDITION
LONG LIFE EDITIONby SEJONGFLEX
They are the R
&D results of Sejong Flex
m
aximizing
the lifetimes of all pro
ducts.
We manufacture only the perfect polyvinyl chloride (PVC) hose products through steady R&D and training of our production workersAs the result of being focused on the research and development to become the best in
the hose industry after the establishment in 1982, Sejong Flex developed the LONG
LIFE EDITION maximizing the lifetime of all Sejong Flex products through the optimal
mixing of raw materials and special treatment.
Products
Sejong Flex has concentrated on one area of the polyvinyl chloride (PVC) hose product resulting in the development
of its specialty.
The steady research and development are being done to make the formula, Sejong Flex = PVC hose, valid.
LONG LIFE EDITION, Sejong’s new brand, symbolizes the best result made with Sejong Flex’s tenacity.
The symbol of LONG LIFE EDITION, the new label of Sejong Flex,
symbolizes the infinity of Mobius,
the flexibility of the hose,
and the initial S of Sejong Flex

LONG LIFE EDITION
High Pressure Spray Hose
●
●
●
●
●
Purpose
For power spray
(For spraying agricultural chemicals for
farm villages, orchards, vinyl green-
houses and so on)
For high pressure water supply
For excavation
(mines, roads and so on)
For cleaning (ships, vehicles and so on)
The other special purposes
●
●
●
●
●
Features
It resists high pressure very much.
The good elasticity and flexibility
obtained from special mixing enables
easy handling.
It is lighter than a rubber hose by 30%
so that it is user-friendly.
It has the strength in wear resistance,
chemical resistance, and weather resi-
stance.
It is the long life edition product so that
it has a long lifetime.
Structure
Especially, both the high tensile strength
of the very high tenacity yarn manufac-
tured with the special twisted-yarn
facility and the strong adhesive power of
the vinyl layer and the very high tenacity
yarn enables the high strength in
pressure resistance. Moreover, the
introduction of the state-of-the-art
adhesion method makes the structure
unchanged in spite of high pressure and
several conditions.
※ The product excluding the one with the specification can be produced on the order basis.
