Tank Connector and Bulkhead Fittings are purpose-built to create secure, leak-proof connections through the wall of tanks, vessels, and containers. Whether used for drainage, fluid transfer, or process integration, these fittings provide a reliable point of entry or exit for liquids, gases, or chemicals. Designed to maintain a tight seal around both the interior and exterior of the tank wall, they are essential in systems where containment and controlled flow are critical.

Key features and benefits of Tank Connector/Bulkhead Fittings.

Key Features

Bulkhead fittings feature integrated gaskets or O-rings to provide a reliable, watertight seal on both sides of the tank wall. This ensures safe containment of liquids, even under pressure or temperature fluctuations.

Key Features

Manufactured from stainless steel, polypropylene, brass, and PVC, they can withstand harsh chemicals, UV exposure, or high temperatures depending on the application. Each material is selected to ensure long-term durability and compatibility.

Key Features

Many designs include both internal and external threads, allowing you to connect pipes, hoses, or valves on either side of the tank. This dual access streamlines installation and increases system flexibility.

Key Features

Available in straight, elbow, and tee designs, bulkhead fittings accommodate different flow paths and space constraints. This allows system designers to adapt fluid movement to meet operational needs.

Key Features

Bulkhead fittings can be easily installed by drilling a hole and securing with a lock nut and washer system. Minimal tools are needed, making them ideal for on-site retrofitting or system upgrades.

Key Features

From cleanroom environments to agricultural water storage, these fittings support hygienic and heavy-duty use cases alike. Smooth interior surfaces and material certifications make them suitable for sensitive media handling.

Tank connector and bulkhead fittings play a critical role in ensuring the safe transfer and containment of liquids. Without a proper fitting at the tank wall, there's a high risk of leakage, contamination, or structural failure under pressure. These fittings allow tanks and vessels to be part of a wider piping or hose system, facilitating both inflow and outflow in a controlled and sealed manner. Their use ensures operational safety, maintains cleanliness in hygienic applications, and protects the environment by preventing spills or exposure to harmful substances. In short, they allow tanks to function as practical and integrated components within complex fluid handling systems.

Tank connector and bulkhead fittings are used in a wide variety of industries and applications. In agriculture, they’re found on water tanks and chemical sprayers; in industrial settings, they connect storage vessels to pump or dosing systems. Food and beverage production facilities use hygienic-grade bulkheads for transferring syrups, dairy, or wash water. They're also essential in aquariums and fish tanks for overflow systems and filtration loops. From clean water applications to aggressive chemical storage, these fittings provide a dependable, sealed connection point where pipe meets tank — wherever fluid control is key.

Industries

Datasheets

Pipeline fittings are used to connect straight sections of pipe, change flow direction, adapt pipe sizes, or terminate a piping system. They’re essential for building efficient, flexible, and safe fluid or gas transport networks.

A fitting joins pipes together or modifies flow (e.g., elbows, tees, reducers), while a flange is a flat disc used to bolt two pipe sections or components together. Flanges allow for easier disassembly and maintenance.

They are commonly made from stainless steel, carbon steel, brass, copper, or plastic depending on the application. Stainless steel and carbon steel are preferred for industrial, high-pressure, or high-temperature systems.

Standard pressure ratings include 150lb, 300lb, 600lb, and higher depending on the material and design. The correct pressure class must match your system requirements to ensure safe operation.

ANSI B16.5 is a standard that defines dimensions, tolerances, and pressure ratings for pipe flanges and flanged fittings. It is widely used in industrial and high-pressure piping systems.

It is not recommended unless proper adapters are used. Mixing standards can result in misalignment, poor sealing, or mechanical failure.

Selection depends on factors such as pressure, temperature, fluid type, pipe size, and applicable standards. Material compatibility and environmental conditions should also be considered.

No. For hygienic applications, only stainless steel fittings with smooth, crevice-free surfaces (often polished) and specific certifications (e.g., 3A, FDA) should be used.

Typical fittings include elbows, tees, reducers, caps, nipples, couplings, and unions. Each serves a unique function in controlling direction, flow, or connectivity.

Common types include weld neck, slip-on, blind, threaded, socket weld, and lap joint flanges. Each type serves a different installation or operational need.

Yes, provided they are rated for the appropriate pressure and temperature conditions. Materials like carbon steel or stainless steel are suitable for steam lines.
