■ Characteristics The length can be adjusted within the L–L1 range. Can be used for both cooling water and oil at 180°C or a lower temperature. ■ Notes on handling Install it in a balanced manner. The structure has allowance of about 1mm in height difference between right and left. However, if it is off balance, excessive load is applied onto the body, which may lead to water leakage.

• JWRF (Flexible plastic tube type) The elbows are connected with a flexible tube, making it possible to go around an obstacle between them. (Recommended distance between the holes is 100mm or longer.) < JWRL Notes for JWRL Usage > E Use the plugs after 5–6 idle rotations with an Allen wrench. Forcing the elastic pipe to extend without idle rotations may result in water leakage.
