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

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.

※ Features and specifications are subject to change without prior notification.

Grit Hose


The construction of the grit hose consists

of a planar inside and a spiral outside that

greatly reduces the resistance during the

movement or transport of an object and

ensures excellent flexibility. The core of

the hose is made of strong rigid polyvinyl

chloride (PVC) resin ensuring it has a

strong resists to both internal and exter-
