Tuf-Tite 4-Hole Distribution Box With Fittings
The 4 hole distribution box includes essential hardware: 3 S-35 seals (Yellow) for thin-wall 4, and 1 P-10 plug (Orange) for unused holes. This setup supports straightforward installation with standard 4″ pipe configurations and provides a tight seal to prevent leaks around connections.
Tuf-Tite 9-Hole Distribution Box with Fittings
This option comes complete with a lid and nine pipe seals, including 9 S35 yellow seals suitable for 4″ PVC SDR35 or similar pipe. It also includes 2 S85 orange seals that allow connections from 1 1/2″ to 4″ schedule 40 pipe, or to seal unused holes on drain sump or distribution boxes. A versatile choice for larger or variable layouts.
Tuf-Tite 7-Hole Distribution Box With Fittings
The 7 Hole Distribution Box includes 7 S-35 seals (yellow) for thin-wall 4, and 2 P-10 plugs for unused holes. This configuration offers a practical middle ground for installations requiring more connections than a 4-hole box but fewer than a 9-hole box.
Tuf-Tite 6 Hole Distribution Box
The 6 hole distribution box includes 5 yellow S35 seals for thin-wall 4, and 1 orange P10 plug for unused holes. This model balances space with seal accessibility, suitable for modest to mid-range septic layouts and irrigation networks.
Tuf-Tite B1-RL Lid for 4 Hole Box
The B1-RL lid is designed as a robust replacement lid for the standard 4-hole distribution box. It features a solid, non-vented surface and interlocking design to ensure a tight seal and protection from water and physical damage. The lid is essential for long-term reliability when the original lid is damaged or worn.

Buying Guide: Key Considerations for 4-Hole Distribution Boxes
- Hole count vs. site needs: Assess the number of connections your system requires. Fewer holes save space and cost, while more holes provide expansion room for future additions or multiple irrigation zones.
- Seal types and compatibility: Look for S-35 (yellow) seals suitable for thin-wall 4″ pipe and P-10 (orange) plugs for unused holes. Compatibility with SDR35, Schedule 40, or other pipe types impacts installation choices.
- Lid and access hardware: A sturdy lid prevents water intrusion and physical damage. Interlocking or ribbed lids can enhance durability in harsh environments. Replacement lids like the B1-RL simplify maintenance.
- Materials and durability: High-density polyethylene (HDPE) boxes resist corrosion and moisture, offering long-term reliability in underground installations.
- Compatibility with risers and extensions: If grading or soil depth requires, consider risers (e.g., 11×11 square risers) to achieve the desired cover height without replacing the entire box.
- Installation environment: For residential and commercial sites, ensure the chosen box handles the anticipated load, exposure to water or chemicals, and potential backfill pressures.
- Replacement parts availability: Having ready access to lids, plugs, and seals minimizes downtime during maintenance or repairs.
Overall, the selections above provide a spectrum of options—from compact 4-hole configurations to larger multi-hole designs and reliable lid components—allowing professionals and DIY homeowners to tailor a septic distribution solution to specific pipe sizes, site constraints, and future expansion plans. When evaluating options, prioritize seal integrity, lid durability, and compatibility with your existing 4″ piping and trench layout.
