Sioux Chief 9958 Rubber Slip Joint Washer, 1-1/2" x 1-1/4"

Sioux Chief 9958 Rubber Slip Joint Washer, 1-1/2" x 1-1/4"

The Sioux Chief 9958 is a rubber slip joint washer sized 1-1/2" x 1-1/4", built for tubular drain and waste connections where a slip nut threads down and compresses the washer against the pipe wall to form a leak-resistant seal. Molded from rubber for flexible, gap-filling contact, this washer suits P-trap, tailpiece, and other tubular fitting assemblies that step down from 1-1/2" tubing to a 1-1/4" connection, or the reverse, wherever a slip-joint nut and washer combination is used to close the joint. It is manufactured in the United States and packaged in bulk cartons of 1000 EA, making it a practical stock item for plumbing wholesalers and service trucks that regularly replace worn or hardened slip-joint washers during trap and tailpiece repairs.

Key Features

• Trade Size: 1-1/2" x 1-1/4" combination size for slip-joint connections between tubular waste pipes of differing diameters.
• Rubber Construction: Flexible rubber material conforms to the pipe surface under slip-nut compression, helping seat a tight seal without over-tightening the nut.
• Slip Joint Type: Designed to be used beneath a slip nut on P-traps, tailpieces, and other tubular drain-waste fittings rather than a solvent-welded or threaded joint.
• Bulk Packaging: Sold in cartons of 1000 EA, sized for plumbing wholesalers, service trucks, and high-volume contractor use rather than single-unit retail.
• Domestic Manufacturing: Made in the United States.
• Replacement Part: A common maintenance item for re-sealing existing slip-joint connections when the original washer has hardened, cracked, or begun to leak.
