Aluminum-Core Swab Cups — Tubing Size and Temperature Review
| Part Name |
Aluminum-core enquiry; TA/MV and other profiles specified separately |
| Environment |
Specify actual well fluid, additives, sand content and temperature |
| Available Material |
NBR, HNBR or FKM by selected compound; aluminum core by order drawing. Other reinforcement configurations require separate specification.

This listing covers aluminum-core swab cup enquiries with 2-3/8, 2-7/8 and 3-1/2-inch size references. Confirm whether each reference is nominal tubing size and provide the actual tubing bore, minimum restriction and required cup dimensions. An undersize cup requires a defined cup OD and operating clearance; the word undersize does not establish a dimensional reduction.
Related profiles — confirm construction and assembly fit:
TA style: The illustrated TA family uses a molded rubber cup around a specified bushing. For an aluminum-core order, confirm bore diameter, axial length, locating shoulder and retention arrangement, together with the cup profile and load requirements.
MV style: A separate multi-lip cup profile with steel or aluminum bushing options. Select against the drawing and operating requirements; a shared tubing size does not establish interchangeability with TA.
V style: A separate upturned-lip family with light-duty and heavy-duty configurations. Review lip geometry, restrictions and sand conditions for the selected assembly.
For elevated-temperature service, provide continuous and peak temperatures, exposure duration and fluid composition. NBR, HNBR and FKM are compound families with different formulations; confirm the selected compound limits and rubber-to-core bond requirements before assigning an operating temperature.
TUF style: An internally reinforced construction requiring its own model drawing and service limits. Reinforcement alone does not establish a high-temperature rating.
NUF style: A separate rubber cup family with specified bushing options. Confirm the bore, cup dimensions and load conditions before considering an alternative.
Other relative rubber products:
Application enquiry: fluid lifting in oilfield tubing. Include tubing condition, travel restrictions, suspended sand and fluid additives with the operating temperature and assembly requirements.
Packing and shipment :
1: Express shipment for small or urgent orders; confirm destination and carrier.
2: Air shipment: confirm airport or door delivery requirements.
3: Sea shipment for bulk orders; confirm packing and shipment schedule.

Aluminum-core swab cup purchasing details
Confirm nominal tubing size separately from cup OD, cup bore and core dimensions. Provide the mandrel drawing and installation arrangement so the replacement can be matched to the assembly.
For an undersize option, state the required OD and clearance against the actual minimum tubing bore. Include tubing wear, scale or restrictions that affect travel, plus fluid-lifting and sand conditions.
State the temperature profile and fluid exposure with the selected rubber compound. Agree inspection and test requirements before confirming suitability for elevated-temperature service.
Send the tubing bore, cup drawing, aluminum-core interface dimensions, compound requirements, temperature conditions and quantity for a quotation.
