PVC DWV Straight Coupling (Hub x Hub)
Engineered for seamless inline pipe connections in non-pressure gravity-fed drainage architectures, our PVC DWV Straight Coupling provides an airtight, structurally secure bridge between two plain-end PVC lines. Featuring an internal stop ridge to prevent over-insertion and ensure perfect concentric alignment, this sleeve maximizes laminar flow across wastewater and venting applications.
Injection-molded from premium, corrosion-immune virgin polyvinyl chloride compounds meeting ASTM D2661 and ASTM F891 criteria, this fitting is highly resistant to aggressive sewer sewer gases, electrolytic deterioration, and standard structural shifting forces.
Key System Performance Baselines:
- Application Profile: Strictly engineered for residential and commercial gravity-fed drain, waste, and vent lines.
- Internal Alignment Stop: Built-in structural center stop ensures consistent pipe penetration depth and solid joints.
- Connection Matrix: Hub x Hub (Socket x Socket) configuration engineered to receive matching Schedule 40 or DWV dimensions flawlessly.
- Material Assurance: Certified to NSF Standard 14 for reliable physical compound properties and dimensional uniformity.
⚠️ Engineering Disclaimer: This component is engineered purely for non-pressure plumbing infrastructure. NEVER apply hydrostatic or pneumatic pressure tests to this fitting, as doing so voids compliance and creates an immediate burst hazard.
