1 inch PVC Schedule 40 Cap

1" PVC Socket Cap – Solvent Weld Fitting for Non-Pressurized and Drainage Applications

The 1" PVC Socket Cap is a solvent-weld fitting used to seal the end of a Schedule 40 or Schedule 80 PVC pipe in non-pressurized or low-pressure systems. Designed for use in gravity-flow drainage, venting, and irrigation configurations, this cap provides a permanent closure point for maintenance or future system expansion.

Molded from durable polyvinyl chloride (PVC) and manufactured in compliance with ASTM standards, the fitting offers reliable resistance to chemical corrosion, UV exposure, and internal system stress. It is suitable for both indoor and outdoor use, including underground installations when properly supported and joined.

Key Product Features

• ✅ Schedule 40 Construction – Compatible with standard 1" nominal diameter Schedule 40 PVC pipe for solvent weld applications.
• ✅ Socket Connection – Accepts pipe via solvent-welding for a permanent and pressure-rated joint.
• ✅ Chemical Resistance – Ideal for gray water, venting, and low-pressure irrigation systems exposed to chemicals or moisture.
• ✅ Non-Metallic Durability – Will not rust or corrode, even in aggressive or buried environments.
• ✅ Meets Applicable Standards – Compliant with ASTM D2466 for PVC fittings and NSF-listed for use in non-potable water systems.

Technical Specifications

• Material: PVC (Polyvinyl Chloride)
• Size: 1 inch nominal
• Connection Type: Socket (Slip)
• Applicable Standard: ASTM D2466
• Service Type: Gravity drainage, venting, low-pressure irrigation

Installation Guidelines

Install using PVC primer and solvent cement per ASTM D2855 for a fully bonded joint. Ensure the pipe end is square-cut, deburred, and clean before assembly. Hold the joint in place briefly after insertion to allow proper set time. Allow for full cure prior to testing or backfilling.

Common Applications

This cap is typically used to terminate open pipe ends in DWV (Drain, Waste, Vent) systems, lateral cleanouts, landscape irrigation lines, and piping stub-outs for future connections. Also suitable for capping off lines in non-potable fluid systems and dry vent terminations.

Code Compliance Note

This fitting is not rated for pressurized potable water systems. For pressure-rated or potable installations, use a cap marked and listed accordingly under NSF/ANSI 61 and pressure class specifications.

The 1" PVC Socket Cap is a standard component in non-pressurized PVC piping layouts, providing a durable and permanent seal for line terminations. Built for long-term reliability, it offers chemical resistance and structural integrity in residential, commercial, and utility applications.
