Part number 57N47 is a 3/32-inch TIG collet in the WP-27/27-series consumable family. Before ordering it, verify both the tungsten diameter and the torch family. Matching only the 3/32-inch size is not enough because TIG collets that look similar can belong to different torch systems.
Arc Weld currently lists the Anchor 57N47 Collet, 3/32 inch, Pack of 2 as an active in-stock product. The store SKU is 57N47. Current stock was verified through the connected Arc Weld Inc. Shopify catalog on October 11, 2026. Stock changes, so recheck the listing before ordering.
What 57N47 identifies
The strongest fitment evidence is the manufacturer-family part numbering. CK Worldwide’s current price list identifies 57N47 as COLLET 3/32" WP27. The same series lists 57N45 for .040 inch, 57N46 for 1/16 inch, 57N48 for 1/8 inch, and larger sizes after that. That sequence confirms that the number is tied to both a tungsten diameter and a torch-consumable family.
That means the buying question is not simply, “Do I run 3/32 tungsten?” It is, “Does my torch use the WP-27/27-series front-end parts that include 57N47?” If the answer to either part is unknown, stop and verify the torch model or existing consumable number.
Three checks before you order 57N47
1. Confirm the tungsten diameter
57N47 is the 3/32-inch size. Measure or read the tungsten package rather than judging by eye. A collet that is too large may not clamp the tungsten correctly. A collet that is too small is not a substitute and can be damaged if forced.
2. Confirm the torch family
Check the torch body, handle label, parts breakdown, or the part number on the removed consumable. CK Worldwide’s current documentation ties 57N47 to WP27. Other supplier cross-reference data also places 57N47 in 27-series applications. Do not use a generic “17/18/26/27” marketplace description as your only proof of fit; aftermarket listings sometimes group physically similar consumables too broadly.
3. Match the whole front-end stack
A collet works as part of a system with the torch head, collet body or gas-lens body, cup, insulator or gasket where applicable, back cap, and tungsten. If the torch has been rebuilt with mixed parts, the old collet number and current torch model may not tell the same story. Compare the removed parts with the correct torch breakdown before ordering.
When should you replace a TIG collet?
A collet is a wear part. Replace it when it no longer grips the correct-size tungsten reliably, shows heat distortion, has split or deformed fingers, will not seat normally in the collet body, or requires excessive back-cap force to hold the tungsten. Repeatedly overtightening the back cap is not a repair.
If the tungsten slips with a new correct-size collet, inspect the collet body, back cap, torch head threads, and consumable stack. A worn collet body or mismatched front-end parts can produce the same symptom as a bad collet.
Common wrong-part mistakes
The first mistake is ordering by tungsten diameter alone. Many TIG torch families use 3/32-inch tungsten, but their collets are not automatically interchangeable. The second is assuming a marketplace cross-reference overrides the torch manufacturer’s parts list. The third is changing only the collet after a torch has been overheated or cross-threaded. When the front end has visible heat damage, inspect every mating component before returning the torch to service.
A quick shop test for tungsten slip
With the power source isolated and the torch cool, install the known-correct tungsten, collet, collet body, cup assembly, and back cap. Tighten the back cap normally. The tungsten should remain secure without abnormal force. If it still slides or rotates, do not simply tighten harder. Disassemble the front end and inspect for a wrong-size collet, worn collet, worn body, debris, damaged threads, or a mixed consumable family.
For a full part lookup, use the WSP Find My Part tool and start with the torch model or the number stamped on the existing consumable. The WSP TIG Support section is the better starting point when you know the torch family but not the consumable number.

Safety and service limits
Disconnect and isolate welding power before changing torch consumables. Let the torch cool before handling the cup, collet body, or tungsten. Do not operate a torch with cracked insulation, damaged threads, a leaking gas path, or visibly overheated front-end parts. If a torch has sustained electrical or heat damage beyond normal consumable wear, follow the torch manufacturer’s service guidance.
Bottom line
57N47 is a useful exact part number because it narrows the selection to a 3/32-inch collet in the WP-27/27-series family. Confirm tungsten size, torch family, and the rest of the front-end stack before ordering. If any of those three checks fail, the correct answer is Unknown — verify before purchase.
