A 4500 gallon Snyder ASTM tank with the heavy wall for 1.9 specific gravity
Snyder part number 7420000N45 is a 4500 gallon vertical liquid storage tank in white polyethylene, 102 inches in diameter and 142 inches tall, shipping at 1300 lb. The wall is rated for liquids up to 1.9 specific gravity, almost twice the weight of water. On top is an 18 inch threaded vented manway. The product name carries an ASTM designation, and No outlet fitting is listed; tell us the outlet you need and we will confirm what can be fitted before it ships. Snyder molds it in Chowchilla, CA and Lincoln, NE.

When the 1.9 wall is the right call
Specific gravity is the weight of a liquid compared with water. Many of the chemicals plants store in bulk are well above water: strong caustic, many acids, brines, and concentrated treatment chemicals. A tank wall rated for 1.9 is thicker, so it carries those liquids at full height without overstressing the lower wall where the pressure is highest. Full of water this tank holds 37,530 lb (4500 x 8.34); filled with a 1.9 liquid, 71,307 lb (4500 x 1.9 x 8.34). Choose the rating by the heaviest liquid the tank will ever hold, not the one it holds today, and check the chemistry in our chemical compatibility guide.
Our listing names ASTM without a standard number. If your project spec calls out ASTM D1998, tell us and we will get Snyder's written confirmation for the submittal. Our article on HDPE tank wall thickness and the ASTM D1998 sizing logic explains where these walls fail and why. For a water reserve instead, see the fire water reservoir guide.
What to confirm before you buy
- Outlet and fittings. None listed. Tell us the outlet size, the fitting and gasket material for your liquid, and any fill, vent and level connections.
- Temperature. No temperature limit is listed for this tank. Tell us the storage temperature and we will confirm it with Snyder before you order.
- Manway. An 18 inch threaded vented manway on top, 142 inches up.
- Pad. Up to 71,307 lb on a 102 inch circle needs an engineered, level concrete pad wider than the base; our concrete pad sizing guide covers the framework. Most chemical sites also need secondary containment around it.
- Drawing. The drawing on this page is Snyder's drawing for the black heavy duty 4500 gallon tank (7420000C34). Ask us to confirm details for this tank.

Shipping and receiving
The tank ships LTL at 142 by 102 by 102 inches and 1300 lb, from Chowchilla, CA or Lincoln, NE. Get the cost to your ZIP from the freight cost estimator. At 1300 lb it needs a loader or crane and straps around the body to unload. Check 7420000N45 on the bill of lading and compare the installed fittings with your order. Fill it with water first and check each fitting before the chemical arrives.
