Pipe Fitting & Valve Component Kit Bags — 8" x 8" / 4 Mil LDPE / Reclosable / 1000 per Case

These 8" x 8" reclosable bags are built for industrial and hardware applications where a square footprint matches the packaging geometry of kitted components — pipe fitting sets, valve repair kits, gasket assortments, and hardware sample packs. At 4 mil, the bag handles the weight and edge sharpness of metal components without puncturing on the zipper track. The reinforced side-welded zipper withstands repeated open-and-close cycling on kitting lines and service counter applications.

Specs: 8" x 8" | 4 Mil | LDPE | 1000/CS | FDA/USDA Compliant

Applications

Pipe fitting and valve component kit bags, gasket and O-ring assortment packaging, plumbing repair kit bags, electrical outlet and switch hardware bags, fastener sample packs, industrial hardware distribution kits, retail display bag for square-format products, wholesale parts program bags.

Features

• Reinforced side-welded zipper — holds up under repeated open-and-close cycling


• 4 mil gauge — handles metal edges, threads, and sharp hardware without puncture


• 8x8 square format — matches geometry of most kitted hardware and fitting sets


• Heat sealable, tie-close, staple, or tape closure alternatives


• Virgin LDPE resin — FDA/USDA compliant for food contact incidental applications


• 1000/CS — high case count for production kitting lines

Material Notes

Manufactured from 100% virgin LDPE (Low-Density Polyethylene) resin meeting FDA/USDA specifications. 4 mil gauge provides the combination of flexibility and puncture resistance needed for metal component kitting. The reinforced zipper is side-welded to the bag body, distributing pull force across a wider seam area than standard track attachment.

Use Case Notes

The square 8x8 footprint is efficient for products that don’t pack well in a tall, narrow bag — O-ring assortments, gasket kits, flange bolt sets, and compression fitting packs. The 4 mil gauge handles the weight of a full pipe fitting set (1/2" to 1" PVC or copper fittings) without the bag stretching out of shape. For retail display, the square format sits flat on peg hooks without folding or collapsing.

Common Questions

Is the zipper rated for repeated use?
Yes. The zipper track is reinforced and side-welded to the bag body for use on kitting lines and service counter applications where bags are opened and resealed frequently.

Can this bag be heat sealed for permanent closure?
Yes. In addition to the zipper, the bag can be heat sealed, stapled, or tape-closed for a permanent closure above the zipper track.

Is this bag FDA compliant?
Yes. Manufactured from 100% virgin LDPE resin meeting FDA/USDA specifications for food contact applications.

Why Buy

The 8x8 square format at 4 mil is a gap filler between small parts bags and large shipping bags. It handles hardware kits, fitting sets, and component assortments that are too heavy for 2 mil bags and too wide for narrow rectangular bags. The 1000-count case supports continuous kitting production without frequent carton changeovers.
