Whether you're a homeowner setting up rainwater harvesting, a gardener connecting a barrel tap, or a DIYer plumbing an IBC container, a poorly fitted bulkhead is the first point of failure. These brass bulkhead fittings are built to give you a solid, leak-free through-wall connection the first time.\u003c\/p\u003e\n\u003cp\u003eEach fitting is machined from solid brass and available in three pipe sizes — 1\/2\" (DN15), 3\/4\" (DN20), and 1\" (DN25) — with lengths ranging from 24mm (≈15\/16\") up to 100mm (≈3-15\/16\") to accommodate different tank wall thicknesses. Thread type options include Male Thread (external thread on one end) and Male \u0026amp; Female Thread (external on one end, internal on the other) for through-wall connections requiring attachments on both sides.\u003c\/p\u003e\n\u003cp\u003eTypical applications include garden water butt tap installation, IBC tote tank outlets, rainwater collection barrel fittings, and agricultural water storage connections. The BSP thread standard ensures broad compatibility with standard garden hose connectors, ball valves, and tap fittings used across the US and internationally.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- ② COMPATIBILITY BAR --\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e BSP (British Standard Pipe) thread — fits standard 1\/2\", 3\/4\", and 1\" BSP taps, valves, and hose connectors.

Generally, the fitting length should be at least 10–15mm longer than the wall thickness. For example, a 5mm tank wall typically works well with a 24mm (≈15\/16\") or 35mm (≈1-3\/8\") fitting. If your tank wall is thicker — such as an IBC or heavy-duty barrel — choose a longer variant like 50mm (≈1-31\/32\") or 70mm (≈2-3\/4\").

These brass bulkhead fittings are designed to pass through a drilled hole in the tank wall and seal with a nut and washer.
