PK Series Triple Branch Union Push-to-Connect Fittings (PK, PKG)
PK Series Triple Branch Union Push-to-Connect Fittings
PK and PKG fittings are used when one pneumatic tube layout needs several branch outlets from a compact fitting body.
PK is the standard triple branch union type. The tube ports use the same outside diameter, so it is suitable when the connected air tubes keep the same size.
PKG is the reducer triple branch union type. It is used when the branch connection needs different tube sizes in the same fitting.
This type of fitting is useful in control boxes, valve groups, air panels and small machine layouts where several tubes need to be arranged close together.
