For Safety's sake

Be sure to read the following before use.

These Bridgestone products are developed for hydraulic components.
Follow each product's application and specification.
Avoid burst, leakage and other dangers by following these important steps.

1 Proper usage

Warning

Do not touch a pressurized coupler or swivel joint.: If a product is broken, and a fluid touches the skin, even if no pain is felt, a serious injury including burns may be caused. Obtain medical assistance immediately. Failure to do so can result in the loss of the injured body part or death. Use of plastic hose guards will increase the possibility to protect a person from injury.
Do not apply an electrical current to a hose assembly.: Electrifying may lead to a product failure or electric shock.
System working pressure should not exceed the rated working pressure.: Exceeding the rated working pressure of hose and coupler may result in the hose bursting or hose coupling-blow off.
Follow the maximum working pressure ratings listed in this catalog.
Use compatible hydraulic fluid.: The use of an incompatible hydraulic fluid will deteriorate the inner tube and or the reinforcement resulting in the hose bursting or hose coupling blow-off.
Do not remove BI coupler under pressurized conditions.

Caution

Avoid the usage exceeding applicable temperature: The usage exceeding applicable temperature may cause leakage and hose coupling blow-off.
Avoid excessive vibration: Excessive vibration may cause leakage and hose coupling blow-off by fatigue.
Avoid vacuum pressure: Excessive vacuum pressure may result in the inner tube damage which will lead to hose failure.
Never repair or rework.
Avoid submerging hose assemblies in water or any other liquid.
Do not take remaining pressure by hitting head portion of poppet of BI coupler
Do not use body or nose of BI coupler as stop valve.

2 Installation

Caution

Follow the below tightening torque. Improper tightening may lead to deterioration of seal performance, oil leakage, and failure of connection portion which may result in injury or material damage.

2 In case of brass or copper

Size	04	06	08	12	16	20	24	32
Size	1/4"	3/8"	1/2"	3/4"	1"	1 1/4"	1 1/2"	2"
Tightening Torque N•m	15	25	29	59	88	118	137	206

Please connect a hose at a right angle to the fixed side like (B).
Avoid the piping like (A) which may apply too much force on the rotating part.

As for installation of swivel joint, fix the shaft side and rotate the housing side.

Do not connect a swivel joint with another swivel joint.

3 Warranty Period

Warranty period is impulse cycle number or each specified period, whichever comes earlier.

4 Preventive Maintenance

Before every usage, check any leakage from the products. If found, replace with a new one.

5 Storage

-Store in a dark and dry place at the temperature between -10℃ to +40℃(14°F to 104°F)

For safety's safe, list the above warnings in your catalog in order to avoid miss-use of products by end users.

Structure

Pressure

JIS Pressure Wave( ISO Pressure Wave )

Proof pressure is maximum working pressure x 1.33. In case of jack application, proof pressure is the same as maximum working pressure.

JL series passed 400,000 impulse test with JIS pressure wave. These products passed 100,000 times Swing test (Swing Angle 120°, Swing speed 15 cpm )
JR series passed 100,000 rotation of maximum working pressure enclosure test (100 rpm )
