Hydraulic / pneumatic and hydraulic / electric-pinch off tools

Models: HY-187, HY-250, HY-500, HY-750, HY-1.0

The HY-series hydraulic / pneumatic and hydraulic / electric pinch-off tools are design to hermetically seal OFHC copper or annealed aluminum tubing with no secondary sealing required after the pinch (solder, braze, etc.). These tools are available in 5 different sizes to accommodate tube diameters ranging from 0.187" through 1.0".  Teamed with the appropriate hydraulic pump, these tools will provide a true hermetic (cold weld) joint for critical applications where the tubing must not, and cannot, leak.  If you are considering the use of these tools for a pinch-off application, we strongly suggest you submit a sample of your tubing to CPS for evaluation prior to ordering. More specific information on the tool is located in the product section below.


Example of OFHC copper and aluminum tube that has been pinched-off and cold welded using HY-series Hydraulic Pinch-off tool

Example of tubing pinched off, cold welded, and hermetically sealed

Tubing has been pinched off and sealed using the HY-series hydraulic pinch-off tools.  OFHC copper and high purity nickel tubing is ideal for this application.  Tubing must be very clean and free of oxidation and other contaminants to achieve a permanent, cold welded hermetic seal.  More details on materials and processes can be found in the HY-hydraulic pinch-off tool catalog at the bottom of the product section.


Standard pinch-off jaws

All of the pinch-off jaws are built (standard) with a 45 degree angle.  Custom jaw angles can be provided, if required.  Each jaw set is equipped with precision ground carbide pinch rollers to insure the cold welded joint is hermetically sealed.  Tube hardness is a critical component in achieving a cold welded joint, so consult with CPS regarding your application prior to considering this tool for your process.


Hydraulic Pinch-Off handsets, Model #HY-187, #HY-250, #HY-500 and #HY-750. Teamed up with appropriate hydraulic pump to complete the systemPinch-off tool models available

We offer 5 models of hydraulic pinch-off tools. Model #HY-187 (for tubing 0.187" diameter or less), Model #HY-250 (for tubing .0.250" diameter or less),  Model #HY-500 (for tubing 0.375"-0.500" diameter),  Model #HY-750 (for tubing 0.625" - 0.750" diameter),  Model HY-1.0 (for tubing from 0.875-1.0" diameter).  Any of these handsets can be used with any of the available pump options offered by CPS  (pneumatic / hydraulic or electric / hydraulic).

 

Hydraulic pump systems for use with pinch-off tools

The hydraulic pumps are available configured as either hydraulic / pneumatic or hydraulic / electric.  The hydraulic / pneumatic pumps require a minimum of 100 - 120 p.s.i. air pressure to properly build hydraulic pressure.  If your shop air is less than 100 p.s.i., you may want to consider using the hydraulic / electric pump as an option.  When ordered as a complete system, the pump is calibrated to work properly with your tube pinch-off (cold weld) application.  (Click on the image to view a larger photo).  For very high volume applications, contact CPS,

F-Style hydraulic pump with remote footswitch for use with any of the HY-series handsets.  For medium volume applications   STANDARD hydraulic pump with  footswitch mounted on pump body,  for use with any of the HY-series handsets.  For small volume applications  E-Style, Electric model hydraulic pump for use with any of the HY-series handsets.  For medium volume applications


Any of the hydraulic pump options shown in this section will work with any of the pinch-off tool handsets.  The volume of tubes being processed will often dictate which pump is best suited for the application. If compressed shop air is not available (minimum 100 psi), the electric pump option is a viable choice.  For very high volume production applications, contact CPS for a pump recommendation.
