Nitrile Aluminum-Core Swab Cups — 2-3/8, 2-7/8 and 3-1/2 Inch Size References
Shanghai Qinuo supplies rubber swab cups for fluid-lifting enquiries. For the aluminum-core item, specify the cup profile, mating mandrel dimensions and actual tubing or drill-pipe bore. The listed inch sizes are selection references; confirm cup outer diameter, bushing bore and assembled clearance from the approved drawing. Nitrile compound selection depends on fluid formulation and operating conditions.
Swab cup profiles and assembly selection:
TA style: A medium-load profile built around a steel or aluminum bushing, as specified for the item. Review the rubber body, bushing bore, support shoulder and compression under load against the mandrel assembly. An aluminum-core order should identify the aluminum bushing drawing rather than assume every TA option uses the same core.
MV style: Multiple upturned lips and a steel or aluminum bushing distinguish this profile. Provide actual bore, restrictions, suspended-solids content and lifting conditions for selection. Lip geometry and bushing fit must be checked together; similar nominal size does not make MV and TA interchangeable.
V style: A rubber cup profile selected with lip geometry, load and bore restrictions. Confirm whether the proposed item requires a bushing or other support and specify cup quantity and assembly arrangement. Do not transfer an aluminum-core specification to a V profile without a drawing.
For fluids containing frac-fluid additives or suspended sand, specify the exact formulation, solids content, temperature and wear requirements. Compound suitability needs application-specific data; a frac-fluid label alone does not establish chemical or abrasion resistance.
TUF style: A profile with internal metal reinforcement as defined by its drawing. Review reinforcement, cup dimensions and mandrel fit for the intended bore and load. Well depth or temperature alone does not establish suitability.
NUF style: A heavy-load profile with bushing construction specified for the individual item. Provide lifting conditions, bore dimensions and mandrel support details. Confirm the load capability through the complete assembly specification.

Application review: tubing or drill-pipe bore, mandrel interface, fluid composition, temperature and lifting conditions.
Packing and shipment :
1: Express: S.F. ,DHL,UPS, TNT, FedEx ect, for urgent and small order.
2: Air shipment: air port to air port or air port to door.
3: Sea shipment: suitable for bulk goods. it will takes more longer time than air shipment.
Shanghai Qinuo Industry provides custom rubber, plastic and machined parts for industrial applications.
Swab cup enquiries should include the profile drawing, bushing material and mandrel interface dimensions.
Send the bore data, sample or drawing, quantity and required inspection documents for production review.
The company operates an ISO 9001 quality management system. Specify any product-specific material and test documentation with the order.

Aluminum-core swab cup ordering checklist
Identify the required profile and the aluminum bushing bore, length, support shoulders and fit tolerances. Include the smallest bore or restriction through which the assembly must pass.
Check rubber-to-core condition and dimensional fit during acceptance. For replacement parts, inspect the mandrel and supporting components; a worn cup sample may no longer represent the original dimensions.
Confirm nitrile compound compatibility with the fluid and cleaning chemicals, normal and peak temperatures, solids exposure and intended lifting cycle. Keep profile, compound and core drawing linked on the purchase specification.
Send the cup drawing or sample, aluminum-core details and service conditions for a replacement enquiry.
