Easy to mount on flat surfaces, horizontally or vertically. Excellent for pressing and assembly operations, with very high forces available.

Clamping Action 
Applying fluid pressure retracts the plunger. Spring return to extended position.
Mounting and Fluid Connection 
Several possible mounting methods: 1) insert four socket-head cap screws from the plunger end, through the four counterbored holes parallel to the plunger; 2) insert four socket-head cap screws from the bottom end, through the four counterbored holes parallel to the plunger; 3) insert two socket-head cap screws through the two broad-side holes perpendicular to the plunger (drilled by the user in the locations shown on Dimensions page). Method 3 requires that the Block Cylinder be backed up for pressures over 2300 psi by a rectangular strip or dowel pins with a height at least 1/3 of the B dimension.

1/4″ BSPP port. Do not use NPT fittings.
Optional Viton Seals 
For high-temperature applications (212° to 300° F), we offer Viton seals in all sizes. Viton seals have a slightly shorter service life. Please contact factory for more information.
