Universal Ball Dome Flanges

Universal Ball Dome Flanges


These flanges are “self-aligning,” which allows for vertical plumbing on the dome of the tank up to 22 degrees. The fitting can be repaired and maintained externally without tank entry. Available with Ryton® bolts, an economical alternative to titanium, C-276, and Alloy 400.
Universal Ball Dome Bulkheads

Universal Ball Dome Bulkheads


Our Universal Ball Dome Bulkheads are also “self-aligning,” which allows for vertical plumbing on the dome of the tank. An economical alternative to UBD flange-style bulkheads, since no additional bolts are required.
Made-Vertical Fittings

Made-Vertical Fittings


Made-Vertical Fittings are fabricated per the customer’s requirements. They are typically used for larger domes that require a fitting to be above 4 inches and in those few cases where our domes are extremely steep. They may need to be supported independently of the tank. For optimal support, install it on a tank runway or as close to the edge as possible.
Flange Adapters

Flange Adapters


Includes a nipple and flange for connection to plumbing system
Bolted Flange Fittings

Bolted Flange Fittings


Available in PVC and CPVC. With these fittings, all aspects of fitting maintenance can be done externally, with no tank entry required. These can be installed on sidewall or dome. Bolt heads are encapsulated in polyethylene, providing chemical resistance.
Bolted Spool Fittings

Bolted Spool Fittings


The Bolted Spool Fitting is fabricated per the customer’s requirements and is typically used for larger dome and sidewall connections. Use a Van Stone flange to connect piping. Bolted Spool Fittings 8 inches or greater are manufactured with gussets.
Bulkhead Fittings

Bulkhead Fittings


An economical fitting best used on small tanks in mild applications. Can be installed on sidewall, overflow or dome. May be used as a overflow fitting with all chemicals, since it’s non-wetted. Bulkhead Fittings must be installed from the inside of the tank, requiring tank entry for repairs and maintenance. They should not be used on tanks greater than 3,000 gallons or tanks greater than 6 feet in height.
The B.O.S.S Fittings

The B.O.S.S.™ Fittings


This one-piece sure-seal fitting prevents leaks and adds value to your tank installation. Its one-piece design reduces the seal point to a single gasket, and its polyethylene construction ensures chemical compatibility. Its back ring design reduces stress on the fitting and makes it three times stronger than similar plastic fittings.
Butterfly Valves

Butterfly Valves


Being slim and light weight yet robust, makes this the ideal shutoff valve for IMFO® drain.
Ball Valves

Ball Valves


Complete line of high-performance Ball Valves to meet varying needs.
Flexijoint Expansion Joints

Flexijoint® Expansion Joints


These flexible PTFE connectors and tremor barriers are designed to compensate for misalignment, absorb expansion and contraction, and isolate the vibration and shock that could damage a tank. Their low spring rate protects stress sensitive connections. Can be installed directly to the dome of the tank to overcome piping misalignment
Combination of Internal and External Fill / Discharge Drop Pipes

Combination of Internal and External Fill / Discharge Drop Pipes


Fill Line assemblies are available in PVC and CPVC with sizes ranging from 1 to 3 inches and include a true union for quick assembly. When choosing a fitting, be sure to consider if the fill will be placed on the flat of the dome; otherwise it will require a self-leveling fitting.
Mushroom Vents

Mushroom Vents


For day tanks, an economical alternative to traditional U-vents or fittings. Made of polypropylene, in sizes 1 to 3 in.
U-Vents

U-Vents


Standard venting for outdoor tanks or for storing chemicals that create fumes. In PVC, in sizes 2 to 6 in.
Safe-Surge Manway Covers

SAFE-Surge™ Manway Covers


Designed specifically for pneumatic-filled tanks. Releases at a 6-inch water column to prevent over-pressurization, ensuring that the tank maintains proper ACFM at all times - even in the event of air surges that cannot be handled by primary venting. Available in 19 and 24 inches. For detailed venting requirements, please refer to the chart.
Bolted Manway Covers

Bolted (8/16) Manway Covers


These are the most popular covers we provide. They are available in 24 inches. Please note that if you plan on visually inspecting the interior of the tank with some frequency, our SAFE-Surge™ manway cover may be a better alternative.
Threaded Lids

Threaded Lids


Available in two sizes, 7 and 17 inches, coarse threaded. Gasket materials available include EPDM, fluoroelastomer, fluoroelastomer GF, XLPE or Buna.
Fume-Tight Manway Covers

Fume-Tight Manway Covers


Available in two sizes, 17 and 24 inches, with bolts of stainless steel, Alloy C-276 and titanium. Gasket materials available include EPDM, fluoroelastomer, fluoroelastomer GF, XLPE or Buna. The 17-inch model is often used on 19-inch manways as well.
Heat Pads and Insulation

Heat Pads and Insulation


Poly Processing’s tank heating systems are specifically designed for temperature maintenance of polyethylene tanks. SilcoPad® tank heating systems maintain a desired product temperature, not to exceed 100° F.
