3-1/2″ x 2-3/8″ Slip Insert for Varco Style Slips | Part 20160
The 3-1/2″ x 2-3/8″ Slip Insert (Pan P/N: 20160) is a heavy-duty reduction insert engineered to adapt 3-1/2″ rotary slips for the secure handling of 2-3/8″ OD drill pipe and tubing. Designed for Varco Style RSST (Short) and RSMD (Medium) slips, these inserts are manufactured from high-tensile forged alloy steel and precision-hardened to API 7K standards to ensure a non-slip mechanical grip without compromising pipe wall integrity.
Description
Comprehensive Technical Data
Maximum-Reduction Engineering
Reducing a 3-1/2″ slip to a 2-3/8″ pipe requires a robust 1-inch thick insert. Our engineering ensures these thick-profile inserts maintain structural stability:
Anti-Deformation Tooth Profile: The precision-machined “bite” is calibrated to distribute radial clamping forces evenly, preventing “bottlenecking” of thin-walled 2-3/8″ tubing.
Forged Strength: CNC-machined from forged 8620 alloy steel, offering superior grain structure compared to cast alternatives.
Controlled Case-Hardening: Heat-treated to 58-62 HRC. This provides a rock-hard gripping surface while the core remains ductile enough to absorb the intense “shock loads” of setting the slips.

Equipment Compatibility
Varco Style Slips: Optimized for RSST (Regular Slip Short) and RSMD (Regular Slip Medium).
Workover Rigs: Ideal for high-frequency tubing handling on land-based service rigs.
Drilling Units: Compatible with SDML and SDXL slip bodies utilizing 1-inch reduction inserts.
Key Performance Advantages
Optimized Grip Consistency: Engineered to penetrate through pipe scale and heavy drilling fluids for a secure mechanical hold.
Precision Seating: Machined to exact tolerances to prevent “insert roll” or vibration within the slip body.
Extended Wear Life: Superior heat-treatment prevents teeth from “rounding off” under high-frequency use.
Rig Floor Safety: Standardized 2-3/4″ length ensures rapid and safe field replacement during pipe size changes.
