Company Profile
Zhuji Huihong Machinery Co., Ltd. is listed as the supplier of this copper round gasket. The company's product portfolio on the platform includes refrigeration, fitting, series, valve, safety valve, plumbing, and fittings categories. While this SKU is one hardware accessory, the seller's broader presence in refrigeration and valve-related products suggests a focus on sealing and connection components. Procurement teams evaluating this gasket should note that the listing does not specify factory certifications, production capacity, or OEM readiness; those details require direct confirmation with the supplier.
The product is branded under “Sipeilai” with model number SPL-ZTDP, originating from Zhejiang, China. For import managers, this geographic origin is common for small hardware components, but verification of quality systems or material certifications is still recommended before committing to volume orders.
Product Description
The Copper Round Gasket (model SPL-ZTDP) is a plug cap style sealing component designed for use in AC and refrigeration systems, as indicated by its product name and application attribute. The gasket is made of copper, which is known for its malleability and thermal conductivity, but the listing does not specify the exact copper alloy or hardness grade. Its surface treatment is listed as “smooth”, which may aid in achieving a consistent seal surface.
Buyers should examine the dimensional list carefully:
- Compatible Screw Size vs Outside Diameter: The six listed screw sizes (1/4, 3/8, 1/2, 5/8, 3/4, 7/8 inch) correspond to six outside diameters (9.1, 13, 16.3, 19.6, 24.1, 27.8 mm). This pairing suggests a scaling design, but the exact inside diameter is marked as “other” without a numeric value.
- Material: Copper (attribute value), but no alloy specification (e.g., C110, C122) is provided.
- Finish and Style: Smooth surface, plug cap style — useful for precision sealing, but buyers should request photos or samples to verify edge condition.
- Packaging: Sold as single item; one unit package is 1.0 x 1.0 x 0.6 cm and weighs 0.002 kg. This is suitable for sample evaluation or small trial orders; bulk packaging would need to be discussed with the supplier.
No additional attributes such as hardness, thickness, pressure rating, or temperature range are provided in the listing, so technical buyers should request a full specification sheet from Zhuji Huihong.
Applications
The product name explicitly ties this gasket to “AC Refrigeration Washers”, and the category “Other” for application indicates it is not limited to a single equipment type. In operational terms, copper round gaskets of this kind are typically used as sealing washers on flare fittings, valve connections, or compressor access ports in air conditioning and refrigeration systems. The six screw sizes cover common SAE flare nut dimensions, making it potentially suitable for service technicians who encounter multiple line sizes.
Because the inside diameter is listed as “other” and not numerically specified, buyers cannot yet confirm fitment for a specific tubing OD. Procurement teams should map the outside diameter list against their own fitting drawings and request a dimensional drawing from the supplier if necessary.
- Feature: Six compatible screw sizes from 1/4” to 7/8” — Buyer advantage: One SKU may cover several service scenarios, reducing part number proliferation.
- Feature: Copper material — Buyer advantage: Malleable for conforming seal surfaces; but verify alloy for corrosion resistance in specific refrigerants.
- Feature: Smooth surface treatment — Buyer advantage: Potential for cleaner seal without surface roughness causing leakage paths.
No certification or compliance data (e.g., UL, CE, RoHS) is present in the listing; applications requiring formal compliance will need supplier documentation.
Service Highlights
Zhuji Huihong Machinery Co., Ltd. does not list specific trade terms, MOQ, or lead times on this product page. The default SKU price is $0.07 per single piece, which positions the gasket as a low-cost consumable. However, import managers should treat this as an indicative price for a single unit; volume discounts and export packaging are not specified.
- Request a formal quotation with tiered pricing for higher quantities.
- Ask for material composition and dimensional tolerance data.
- Confirm whether the supplier can provide samples before bulk purchase.
- Inquire about MOQ, production lead time, and shipping terms (FOB/CIF).
The seller’s listed product categories include refrigeration, valves, and plumbing fittings, which may indicate experience with hardware components, but no certifications or quality management system details are shown. Buyers should conduct their own supplier audit or request third-party inspection if order volume justifies it.
CTA
Next steps for buyers evaluating this copper round gasket:
- Contact Zhuji Huihong Machinery Co., Ltd. via the platform to request an RFQ with the model SPL-ZTDP and the six specified sizes.
- Request a sample set covering the size range to verify dimensional accuracy and surface finish.
- Obtain a full specification sheet including copper alloy, hardness, inside diameter, and thickness if your application is critical.
- Clarify packaging options and export documentation before placing a trial order.
Because the listing does not state MOQ, OEM customization, or certifications, these are open questions that must be resolved before shortlisting.
