Sioux Chief HARDHAT 8800 Series Temporary PVC DWV Test Cap, USA-Made

Sioux Chief HARDHAT 8800 Series Temporary PVC DWV Test Cap, USA-Made

The Sioux Chief HARDHAT 8800 Series Temporary DWV Test Cap is a PVC cap built for sealing off open PVC DWV and pressure-test lines during plumbing rough-in, available in 1-1/2\" and 3\" trade sizes as models 880-01P and 880-03P. It is not intended for permanent installation, giving plumbing contractors and inspectors a fast, reusable way to hold a line under test before fixtures, traps, and final connections go in. Manufactured in the United States, the HARDHAT 8800 Series holds pressure while a rough-in inspection is scheduled, then comes off once the line is ready for permanent trim-out.

Key Features

• HARDHAT 8800 Series: Offered as model 880-01P (1-1/2\") or model 880-03P (3\") within the Sioux Chief HARDHAT test cap lineup, so crews can match the configuration to the job.
• Reusable Jobsite Tool: Designed to be installed, pressure-tested, and removed, then reused on the next rough-in rather than left in place.
• Country of Origin: Manufactured in the United States.
• Case Packaging: Supplied 500 per case, suited to distributor stocking and high-volume jobsite use.

Why Sioux Chief?

Sioux Chief builds the HARDHAT 8800 Series Test Cap from PVC so it can hold up through the repeated pressure-test cycles of a busy rough-in schedule, and manufactures it in the United States for consistent quality from case to case. Because the 8800 Series ships in both the 880-01P (1-1/2\") and 880-03P (3\") configurations, plumbing contractors can keep the right test cap on hand, seal a line quickly, and move confidently from rough-in through inspection to final trim-out without unplanned delays. With 500 pieces per case, distributors and contractors can stock the HARDHAT 8800 Series at the volume a busy plumbing operation actually needs.
