POOLPOINT manufactures 83 compatible parts in this category, covering the equipment lines American distributors and service companies stock most. Every part is dimensionally checked against an OEM sample before tooling is signed off, so fitment matches the original without modification.
Search by the number stamped on the failed component and the cross-reference table returns the compatible option. If the number is worn away, send a photo — identifying parts from images is routine for us.
Use the brand filters above to narrow the list, or search by an OEM part number for an exact match. Orders start at 50 pcs per SKU with mixed cartons accepted, and private-label packaging is available for distributor programs.
Factory direct. No trading company. All parts ship from our own factory in Wenzhou, by air or sea, FOB or CIF.

Sourcing questions
Request a quoteWhat is your MOQ?
50 pcs per SKU for stocked items. Mixed cartons are welcome — you can combine SKUs to reach the order minimum. Samples are handled separately: we can supply a single piece so you can verify fitment before ordering in bulk.
Can I order samples before a bulk order?
Yes. We ship samples by express before bulk production so you can verify fitment on real equipment.
What are your lead times?
Typically 15–25 days after order confirmation, depending on quantity and whether custom packaging is involved.
Do you offer OEM and private-label packaging?
Yes — custom cartons and labels, your logo molded or printed on parts, and custom molds for volume programs.
