E L–shaped Swivel joint is a product for the turn at the time of mold attachment. Note that intermittent or continuous changing the direction of the swivel joint could damage the O–ring, which results in water leakage.
channel. Press the incoming fluid at this joint, flow volume at the inlet and outlet varies. • By rotating Part A to misalign side hole φ C position, the fluid flow becomes more fluent.
outlet becomes relatively narrower due to different structure from conventional type. • Available to secure constant flow rate at any position by rotating Part A 1 .
