Product Introduction
The 4.5-inch V-style oilfield swab cup is listed for well servicing in compatible casing or tubing where sand and suspended solids may be present. This configuration is identified by a flexible lip and steel-reinforced base. Selection for sand service depends on particle size and concentration, fluid, bore condition and assembly; specify these conditions when evaluating a replacement.
4.5-Inch Reference Dimensions: The legacy range table lists 4.062-inch OD × 2.495-inch ID for a standard 4-1/2-inch steel-core entry, with a separate heavy-duty entry at the same nominal size. Confirm the profile, actual dimensions and mandrel interface for the requested replacement.

Key Features and Engineering Advantages
1. Sand-Service Selection: Particle size and concentration, bore condition and lip wear affect cup selection. Provide these details for a sand-service replacement; this listing does not state a solids-handling limit.
2. Fluid-Lift Configuration: The existing listing identifies light-to-medium load use. Confirm the fluid load and complete assembly limit for the selected cup; no cup or tool-string rating is stated here.
3. Running Conditions: Follow the approved wireline-speed and fluid-entry procedure. Check for restrictions and debris; the V-profile is not a basis for increasing descent speed.
4. Steel-Reinforced Base: The listed construction includes a steel insert. Confirm insert dimensions, retention and mandrel fit from the selected drawing; no extrusion rating is listed here.
5. Cup Stack Configuration: Cup count, spacing and retention depend on the mandrel and operating procedure. Specify the complete assembly and planned load when evaluating a stack.

FAQ
Question: Why should I choose a V type cup over an RTL type for 4.5 inch casing?
Answer: Choose from the actual cup geometry and operating configuration, using the bore condition, fluid load and solids content. Do not infer a comparative load rating from V or RTL naming alone.
Question: What is the role of the steel insert in this light-load cup?
Answer: The steel insert provides a rigid foundation for the cup base. In larger 4.5 inch sizes, this reinforcement is necessary to keep the cup secured on the mandrel shoulder under hydrostatic pressure.
Question: Is the NBR material resistant to crude oil?
Answer: Confirm the NBR compound against the actual crude oil, additives and temperature. Provide fluid details when requesting a replacement.
