Heavy Duty 9" Chemical Resistant NBR Washer Pipe Wiper for Downhole Tool

Our heavy-duty rubber discs and NBR washers serve as high-performance 9" pipe wipers, essential for protecting sensitive downhole tools and ensuring rig floor safety. Specifically engineered for versatile drilling muds, these wipers prevent abrasive cuttings and corrosive fluids from contaminating the rotary table and downstream equipment. Manufactured from premium Nitrile (NBR) elastomers, they offer exceptional oil resistance and mechanical strength. By effectively scraping the drill string during tripping operations, our wipers facilitate maximum mud recovery and reduce environmental impact. These durable 9-inch discs maintain a consistent seal, safeguarding expensive tool joints and downhole motors from premature wear. As a professional manufacturer, we provide these robust sealing solutions to optimize operational efficiency and rig productivity in demanding onshore and offshore oilfield environments.

• Premium NBR Construction: High-grade Nitrile Butadiene Rubber ensures excellent resistance to petroleum-based fluids and standard drilling additives.

• Downhole Tool Protection: Effectively removes rock fragments and debris before they can enter and damage expensive bits or LWD/MWD tool assemblies.

• Superior Mud Recovery: The precision-molded 9" disc provides a tight 360-degree seal, allowing for maximum reclamation of costly drilling fluids.

• Reinforced Tear Resistance: Engineered to withstand the intense friction of thousands of feet of pipe, preventing premature splitting and wear.

Available types of Swab cups:

As a leading sealing manufacturer, we provide not just products, but complete technical solutions. We empower global distributors with extensive OEM capabilities:

• Full Size Range: Production of all industrial sizes up to 30" OD for various casing needs.

• Material Variety: Available in NBR, HNBR, and specialty blends for extreme H2S or high-temp wells.

• Bespoke Packaging: Individual plastic bags or sturdy branded boxes to suit your retail or field needs.

• Laser Marking: Permanent laser etching of your company logo, part numbers, and batch codes for traceability.

• Inventory Coding: Barcode or QR code application directly on the wiper for digital management.
