The heavy-wall 300 gallon tank, ASTM certified
The Snyder 1630100N45 is a vertical liquid storage tank that holds 300 gallons in a white polyethylene shell 36 inches across and 82 inches tall, and it weighs 100 pounds, a third more resin than the standard certified 300 in this shape. That wall is the point: rated for a specific gravity of 1.9, or 4,754 pounds of contents against 2,502 for water, sold with ASTM certification, and built for the tank that will be worked hard and expected to last outdoors. A 10 inch lid on top, a 3 year warranty, and a base that goes through a standard door.

What 100 pounds of resin is for
A rotationally molded tank's empty weight is its wall thickness, and 100 pounds against 65 in the standard certified tank of this size is a shell that resists creep under a dense liquid, holds its shape through years of sun and thermal cycling, and carries a valve and hard pipe at the outlet without oval-ing the fitting. The certification is against ASTM D1998; the HDPE tank wall thickness guide explains the sizing logic and why inspection happens above the liquid line. Full, it puts 4,754 pounds on a 36 inch circle at the rating, so it is strapped to a wall or to anchors. The 300 gallon vertical tank buyers guide compares the class; the tank sizing calculator turns feed rate and refill schedule into a tank size, and the tank sizing guide covers the reserve.
Walls and shapes at 300 gallons
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 1630100N45 (this tank, heavy wall, ASTM certified) | 300 | 36 x 82 in | 100 lb |
| 1630000N45 (ASTM certified) | 300 | 35 x 80 in | 65 lb |
| 1011200C26 | 300 | 35 x 82 in | 85 lb |
| 1011200N42 (XLPE) | 300 | 35 x 82 in | 85 lb |
| 1008200C26 (squat) | 330 | 47 x 50 in | 85 lb |
The 1630000N45 is the lighter certified 300 with an 18 inch manway, 35 pounds less. The 1011200 tanks are the general 300 on a 35 inch base at 85 pounds, with the N42 in cross-linked polyethylene for oxidizers. The 1008200C26 lays 330 gallons down to 50 inches on a 47 inch base for under a bench.

Where the pipe goes
- Access: 10 inch lid; a dip tube takes the fill from a hose or tote pump; a fuming liquid gets a vent line to the outside.
- Outlet: the bulkhead fitting is chosen for the liquid at order time; a short flexible section to the pump, and the valve supported on its own bracket.
- Service limit: 120 F / 48 C.
- Listing: ASTM certification.
A white 82 inch tank shows its level in daylight; a low-level float switch keeps a pump from running dry. The dosing pump sits below the outlet so it primes by gravity, keep the lid closed against vapor loss, and inspect above the liquid line, in the headspace, where a tall wall fails first. A 36 inch tank fits a standard spill pallet.
The work it does
Treatment chemicals at a small system that needs the certification on file and works the tank hard, brine for a softener, acid and inhibitor feed at a cooling tower, and an outdoor tank in full sun; with water in it, a well buffer or a cell of the small fire reserve the fire-water reservoir design guide describes. One liquid per tank, labeled.
Freight, in plain terms
The 1630100N45 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. Two people carry 100 pounds through a door. Strap it, water-fill to the lid and hold it, check the outlet fitting, and keep the certification with the project file. Save the pallet; a tank that ever has to move again is easier to move on it.
Freight and documents
Ships from: Chowchilla, CA. LTL freight is quoted to your ZIP with the freight cost estimator or by phone at 866-418-1777. The listed price is before freight.
