DB-60 PVC Conduit | Direct Burial & Encasement | Bell End | 20' Sticks
DB-60 PVC Conduit | Direct Burial & Encasement | Bell End | 20' Sticks — Product Overview
Prime Conduit DB-60 P&C Duct is a heavy-wall nonmetallic conduit made from a high-modulus PVC compound for power and communications work. Prime designs it for direct burial or concrete-encased installations, and it is rated for use with 90°C cable.
Every 20-foot stick carries one factory-formed bell end for a fast, secure solvent-weld joint. DB-60 meets ASTM F-512 and NEMA TC-6 & TC-8, with a minimum pipe stiffness of 60 lb/in/in. Stocked sizes run 2", 3", 4", 5" and 6".
Priced by the foot and sold in whole bundles. Each size ships in the bundle footage shown in the table below, and orders are placed in multiples of it — one bundle, two bundles, and so on. Partial bundles are not available.
Which Duct Series Do I Need?
| Series | Min. Pipe Stiffness (lb/in/in) | Prime's Stated Use | Listing |

Pipe stiffness is the NEMA TC-6 & 8 / ASTM F-512 minimum for the series — a higher number means a heavier wall and more crush resistance. Important: Prime rates Type EB for concrete-encased installations; Type DB is the series rated for direct burial. Burial depth, cover and duct-bank requirements are set by your local authority having jurisdiction — confirm the series with your inspector or our sales team before ordering.

Weights, outside diameters, minimum wall thicknesses and bundle quantities are Prime Conduit published values from the P&C Duct catalog. Impact resistance is the NEMA TC-6 & 8 minimum at 0°C (32°F). Bundle quantity is the order increment for that size — for example the 6" is ordered as 520 ft, 1,040 ft, 1,560 ft and so on.
Need 3-1/2"? Prime lists a 3-1/2" DB-60 (part 48814-020, 4.000" O.D., 0.107" wall) in its catalog, but it is not on the current price schedule and we do not stock it — ask our sales team for a quote. Prime specifies 3-1/2" Schedule 40 elbows for it, since there is no 3-1/2" DB-60 sweep.
