RSSD Non-Elastomeric Sliding Sleeves

The RSSD Series Non-Elastomeric Circulating Sliding Sleeve is a high-performance pressure-equalizing device that enables tubing-to-annulus connectivity, facilitating fluid circulation and selective zone production. Externally installed, it supports hydraulic packer setting and verifies seal integrity between the packer and tubing string.

Features

• Precision-positioned high-strength thermoplastic diffuser ring controls fluid/gas surge during shifting to protect upper packing and enable gradual high-differential equalization, minimizing tool string damage.
• Mill-slot flow ports (instead of drilled holes) on housing and insert boost flow area, reduce erosion, and enhance torque and tensile strength.
• Threaded connections integrated into the primary seal stack eliminate O-ring thread seals and cut potential leak paths.
• Locking angled torque shoulder allows higher torque and prevents thread back-off; modular design enables RSSD configuration conversion via upper/lower sub swaps, with proprietary non-elastomeric/elastomeric compounds optimizing seal performance for diverse environments.
