Description
A hex head plug closes the open end of a female threaded fitting or valve. It has a male thread and a hexagon head, so you can fit and remove it with a spanner. As a result, it is ideal for drain points, test points and spare branches. We stock forged plugs at our showroom in Nad Al Hamar, Dubai, for same-day collection across the UAE.
First, match the plug thread to the fitting: NPT for most oil and gas skids, or BSPT for water and building services. Next, choose carbon steel A105 for general service or stainless steel 316 for chemicals and seawater. For example, a 1/2″ NPT plug is the usual size for a pump drain.
Why Choose Our Hex Head Plug
- High pressure rating: Because the plug is solid forged steel, it suits Class 3000 and Class 6000 lines.
- Easy removal: The hex head gives a firm grip. Therefore, you can open drain points quickly.
- Tight seal: Tapered NPT and BSPT threads seal well with tape or paste.
- Traceable steel: Also, we can supply EN 10204 Type 3.1 certificates on request.
