Product Introduction

The 2 1/2" SV style swab cup is an NBR rubber and metal-core component for fluid recovery during well servicing. This version is intended for enquiries involving oil exposure and abrasive wear. Specify the fluid composition, operating temperature, sand content and existing cup dimensions so the compound and fit can be confirmed.

The SV sealing profile contacts the tubing wall during lifting. The 2.5-inch designation is nominal: actual tubing inside diameter, cup outside diameter, mounting bore and seating dimensions determine assembly fit. Include photographs of worn lips and the tubing condition when reviewing repeated wear.

Key Features & Advantages

1. NBR Compound Selection for Oil Exposure
Nitrile rubber is used for oil-service sealing applications, but compatibility depends on the selected compound, fluid additives and temperature. Identify crude oil, diesel or treatment chemicals in the enquiry so suitability can be reviewed for the actual fluid.

2. Abrasive Wear Assessment
Sand particles, rough tubing and deposits can abrade the sealing lip. Provide particle size, solids concentration and wear photographs to help assess the replacement profile and inspection requirements; service life varies with operating conditions.

3. SV Style Flexible Lip Design
The flexible SV lip forms the tubing contact surface. Check the lip for cuts, cracking or permanent deformation before reuse. Scale and salt deposits may damage the rubber and should be considered in the operating procedure.

4. Fluid Lifting and Assembly Fit
Fluid recovery depends on cup fit, lip condition, fluid load and the swab assembly. Confirm the mandrel seating and retention arrangement against the existing equipment; cup size alone does not establish the load or pressure rating of the tool.

FAQ

Q1: What is the primary difference between SV and MV type swab cups?
A: SV and MV identify different cup profiles. Compare the actual profile, dimensions, material and assembly requirements against the existing equipment. The style name alone does not establish a load rating or prove suitability for sandy fluids.

Q2: Can these cups be used in sour gas (H2S) environments?
A: This listing describes an NBR version. Sour-service suitability requires review of the specific rubber compound and metal components for the stated H2S exposure, temperature and fluid chemistry. An alternative material name alone does not establish qualification.

Q3: How do I know if the 2 1/2" size is right for my tubing?
A: Supply the actual tubing inside diameter, existing cup outside diameter, mounting bore, seating dimensions and retention details. A drawing or sample helps confirm fit; nominal tubing size alone is insufficient.
