6-Inch Inlet Products

HBI-6610

This section contains 40 1" holes per foot, and is used in standard conditions with 4", 5", and 6" tile (sometimes 8" where the flow capability of an 8" inlet is not needed).
HBI-66SL

This is a 6" x 1" holed section with 5 1"x 4" slots per foot. It is used to provide more flow than a 6" x 1" section can provide where an 8" x 1" section is too much. It can also be used in conjunction with a 6" restrictor to help eliminate trash build-up due to possible restriction of the 1" holes.
HBI-6516

This is a 6" x 5/16" holed orange section used underground from the tee as a riser extension. It can be cut at different locations (as marked on the section) to adjust the height of the inlet.
HBI-66BL

This is an orange blank section that is used for offsetting the inlet from the main line. It can also be used in place of HBI-6516 when no small holes are wanted below ground.
HBI-6BTN

This is a Blind Tee that connects directly to 6" corrugated or dual wall tile.
HBI-66BT

This part is a 6" x 6" New Style Tee to be used to connect directly to 6" corrugated or dual wall tile and has a 6" inlet bell so that a 6" inlet can be snapped directly into the tee without the use of an adapter.
HBI-60R0

This is a 6" resrictor to adjust the flow of water to the main line.
HBI-6540

This is a reducer that connects 5" or 4" corrugated tile to a New Style Tee.
 
HBI-0608I

This increaser adapts a 6" tee to a 8" riser section.
HBI-0610I

This increaser adapts a 6" tee to a 10" riser section.
HBI-0806R

This reducer adapts a 8" tee to a 6" riser section.
HBI-1006R

This reducer adapts a 10" tee to a 6" riser section.

  • Every Hickenbottom® Inlet is made of high-density polyethylene.
  • All Hickenbottom® parts, tees, offsets, risers, and inlets snap together for easy installation. Risers and inlets can be cut to desired lengths.
  • Markings on Hickenbottom® Inlets allow for easy height adjustment. Find the marking for the desired height and simply cut on the line.
  • Hickenbottom® Inlets are lightweight and simple. There is no need to hoist in concrete catch basins and no need to weld aluminum or steel pipe inlets.
  • Hickenbottom® Inlets are durable, easy to see, and easily maintained.
  • Check out Hickenbottom® adapters to increase or reduce the intake of the inlet off of the inletís tee. Contact your local NRCS office to properly size restrictors for your project.
  • A special inner riser may be inserted to maintain ponding at a certain level to improve water infiltration in semi-arid regions.
  • Hickenbottom® Inlets are government approved. There are authorized distributors in the U.S. and Canada that have inlets in stock for fast delivery to contractors.

General Information for Installation Practices

Inlets

Installation for all Hickenbottom® Inlets should be in accordance with specifications for corrugated P.E. piping, such as ASTM F-405 and AASHTO highway specifications M-252. These can be found in the Soil Conservation Service Engineering Field Manual for Conservation Practices in Book 2 of 2, Section 8-82 and 8-83.

When back-filling inlets at shallow depths (less than 24 inches), it is recommended that one bed the tee and underground portion of the inlet with 1/2 to 1 1/2 inches of stone aggregate (ie: limey chips). In normal conditions concerning depths less than 24 inches (up to 72 inches), the spoil from the trench may be used for bedding if the size of the spoil material is less than 2 inches in diameter.

In conditions of 72 inches or deeper, one should surround the vertical portion of the inlet with a circumference of approximately 12 inches of the aforementioned aggregate to the surface.

To keep the vertical portion of the inlet from tipping over in the back-filling process, fill around the inlet in a mounding fashion then taper the slope down and away from the inlet to the bottom of the trench.

Make sure that all Hickenbottom® sections are snapped together before backfilling.

Further questions concerning inlet installation may be directed to the general office at 1-800-443-7879.


New Style Tees
  1. A 6" tile bell may be fitted over a 6" SDR.35 bell or a 6" DR-C900 spigot.
  2. An HBI-654 reducer may be used to connect a 6" inlet tee to 6" field tile. The reducer will fit directly into the bell of the 6" tee.
  3. A Hancor 6" x 5" reducer (product #FC-R05-06) and 6" x 4" reducer (product #FC-R04-06) both fit into a 6" inlet tee bell.
  4. Most 6" reducers work well with this product; however, a piece of 6" field tile may be needed to connect the tee to the tile.

6" Stacks
  1. The spigot of a 6" stack may be fitted with all 6" SDR.35 bell end fittings.
  2. In order to fit a 6" Schedule 40 bell over a 6"stack bell, the 6" stack bell will need to be cut below its rib.
  3. A Fernco plastic adapter may be fitted to a 6" stack spigot. Please refer to NCS chart for further flow capacities.
