PVC Schedule 40 Longline Conduit Coupling — 1 in.
The 1-inch PVC Schedule 40 longline coupling (COUP-LONG-LINE-1) is a 5-inch-long coupling designed for joining Schedule 40 PVC conduit runs. The extended length of the longline design provides additional joint strength and is particularly useful in direct burial and underground conduit installations where joint integrity is critical.
Key Features
- PVC Schedule 40 construction for durability and chemical resistance
- Longline design (5 in. length) for enhanced joint strength
- Snap-on installation
- 1 in. trade size for standard Schedule 40 conduit

Applications
Designed for underground and direct burial PVC conduit installations where standard couplings may not provide sufficient joint length. Used in electrical conduit systems for residential, commercial, and industrial underground wiring runs. The longline length reduces the risk of joint pullout under thermal expansion and soil movement.
