Product Overview
The CAMTOP Manual Sucker Rod Stripper (Rod Wiper) is a manually operated tool designed for cleaning sucker rod surfaces during workover and well servicing operations. It uses replaceable rubber blocks to effectively wipe and clean various sizes of sucker rods, preventing wellbore fluids and debris from contaminating the work floor and surrounding environment.
The tool features a simple yet robust construction consisting of a body, rubber blocks, clamping plates, and adjusting screws. The body and clamping plates are manufactured from high-quality alloy steel using precision casting processes with heat treatment, delivering exceptional strength, rigidity, and durability. The rubber blocks are made from wear-resistant materials for extended service life.
Designed for versatility, the CAMTOP Rod Stripper can be mounted on 3″ LP threaded connections or on any standard tubing or casing connection on the wellhead, making it adaptable to a wide range of rig configurations.

Key Features & Advantages
1. Simple & Robust Construction
Comprised of body, rubber blocks, clamping plates, and adjusting screws — a straightforward mechanical design that is easy to operate, maintain, and repair with minimal training required.
2. Premium Alloy Steel Construction
Body and clamping plates manufactured from high-quality alloy steel with precision casting and heat treatment processes, providing exceptional strength, rigidity, and long-term durability in harsh oilfield environments.
3. Wear-Resistant Rubber Blocks
Rubber sealing blocks made from abrasion-resistant materials effectively clean sucker rod surfaces while withstanding repeated contact. Blocks are easily replaceable when worn, minimizing downtime.
4. Versatile Mounting Options
Compatible with 3″ LP threaded connections on standard rotating blowout preventers (RBOP) and adaptable to any standard tubing or casing wellhead connection, ensuring broad rig compatibility.
5. Adjustable Clamping Force
Twin adjusting screws allow operators to fine-tune the clamping force of the rubber blocks against the rod surface, optimizing cleaning effectiveness for different rod sizes and conditions.
6. Environmental Protection
Effectively prevents wellbore fluids, crude oil, and drilling mud from being pulled to the surface on sucker rods, maintaining a cleaner, safer work floor and reducing environmental contamination risks.
Operating Principle & Application
The CAMTOP Manual Sucker Rod Stripper works on a simple mechanical principle. It is installed at the wellhead (typically on top of the rotating BOP or on a tubing/casing connection) with the rubber blocks facing inward to contact the sucker rod surface.
How It Works
- The tool is mounted on the wellhead using the 3″ LP 8V bottom thread connection
- Sucker rods pass through the center opening during pulling operations
- The rubber blocks make contact with the rod surface, wiping off oil, mud, and debris
- Adjusting screws allow the operator to fine-tune block pressure against the rod
- When blocks wear down, they can be quickly replaced to restore cleaning performance
Typical Applications
Essential for sucker rod pulling and running during well workover, preventing fluid spillage on the rig floor.
Used during routine well servicing to maintain clean rod strings and reduce environmental impact.
Installed when pulling rods for pump inspection, repair, or replacement on beam pumping wells.
Adaptable to any standard wellhead connection for use across various rig types and configurations.

Maintenance & Care
| No. | Maintenance Task | Procedure |
|---|---|---|
| 1 | Post-Operation Cleaning | After each use, rinse the tool with diesel oil or kerosene to remove accumulated crude oil, mud, and debris. Wipe down all metal surfaces to prevent corrosion. |
| 2 | Rubber Block Inspection | Inspect rubber blocks before each use for cracks, excessive wear, or hardening. Replace when blocks no longer provide effective sealing/wiping contact with the rod surface. |
| 3 | Adjusting Screw Maintenance | Keep adjusting screw threads clean and lightly lubricated. Check for thread damage or deformation. Ensure screws turn freely for proper clamping force adjustment. |
| 4 | Thread Connection Care | Clean and inspect the 3″ LP 8V bottom connection thread after each use. Apply thread compound before installation to ensure proper sealing and prevent galling. |
| 5 | Body Inspection | Check body and clamping plates for cracks, deformation, or corrosion. Alloy steel components should maintain structural integrity. Replace if any damage is detected. |
Frequently Asked Questions
Q1: What is the purpose of the CAMTOP Manual Sucker Rod Stripper?
The rod stripper is designed to clean and wipe sucker rod surfaces during pulling operations. It removes crude oil, drilling fluids, and debris from rod strings as they are pulled from the wellbore, keeping the rig floor clean and preventing environmental contamination. It is an essential wellbore fluid control tool for workover and well servicing operations.
Q2: How does the tool mount to the wellhead?
The CAMTOP Rod Stripper features a 3″ LP 8V bottom thread connection that mounts directly to a 3″ LP rotating blowout preventer (RBOP) or similar threaded connection. It can also be adapted to any standard tubing or casing wellhead connection. The 76 mm (3″) top opening accommodates standard sucker rod passage.
Q3: How often should the rubber blocks be replaced?
Rubber blocks should be inspected before each use. Replacement frequency depends on usage conditions and rod surface condition. Signs that replacement is needed include: visible cracks or tears in the rubber, excessive hardening that reduces flexibility, or when the blocks no longer maintain effective contact with the rod surface after maximum screw adjustment.
Q4: What sucker rod sizes is this tool compatible with?
The tool’s 76 mm (3″) top opening accommodates standard sucker rod sizes typically used in oilfield applications. The adjustable rubber block clamping mechanism allows fine-tuning of the wiping pressure to match the specific rod diameter being pulled. For non-standard rod sizes, contact CAMTOP for customized rubber block options.
Q5: What materials are used in the construction?
The body and clamping plates are manufactured from high-quality alloy steel using precision casting processes and heat treatment for maximum strength and durability. The rubber blocks are made from wear-resistant elastomer compounds designed specifically for oilfield fluid contact and repeated mechanical abrasion. All materials are selected for long service life in harsh oilfield environments.
Q6: What is the warranty and spare parts availability?
CAMTOP provides warranty coverage for manufacturing defects in materials and workmanship. Rubber blocks are considered wear/consumable items and are excluded from standard warranty — however, they are available as readily replaceable spare parts. Contact CAMTOP sales for spare rubber block kits, clamping plates, and adjusting screws. We recommend keeping a spare rubber block set on hand for uninterrupted operations.
