Stellarton’s Hold Downs are mechanical hold down and seal devices which locate and lock into nipple profiles in tubing string. Used in conjunction with the Hold Down installation is the Bottomhole Spring Assembly which is installed immediately above the A-Series Hold Downs.

The A-Series Hold Downs provide the most secure lock of any Hold Downs available on the market and offer dependable and trouble free operation. They are used in Interlift installations with or without a Velocity Tube and, should a Velocity Tube be required the A-Series can be easily adapted.

Features:

AS1 Hold Down

• Suited for low pressure, low velocity Interlift applications.
• The AS1 Hold Down is a “friction fit” hold down that can also operate in high pressure.

A1 Hold Down

• The A1 Hold Down is a “locking” hold down that, once sheared, locks securely by expanding into nipple profile recesses.
• Suited for faster moving DynaFlow and Velocity Tube extensions.
