Self-Align Fittings H/DL/L/LL Series Common Specifications (Reference)
A non-directional type sleeve
The sleeve has no directionality and so there is no need to worry about mis-insertions leading to accidents or downtime.
The sleeve helps protect against external damage
The section of the sleeve which engages the workpiece is a single type, giving it a strong edge and ensuring external damage will not easily lead to impaired functionality.
Low pressure loss
Being a structure with no insert, there is only a small amount of flow resistance, allowing a large amount of flow-through.
The product series features a wide variety of models and sizes
There are 10 model types available, including the swivel type. The series includes 5 sizes with applicable tube outer diameters ranging from ø4 to 12 mm, allowing use in a wide range of applications.
