Description
Overview:
The Malleable Iron Blanking Cap 1/2" BSP Self Colour is a threaded end cap used to close off open pipe ends and unused ports, helping to prevent leaks and protect threads. Made from tough malleable iron, it combines strength with a little give, so it resists cracking under tightening. The 1/2 inch BSP female thread (approximately 12.7 mm / 1.27 cm nominal) suits standard BSP pipework found in plumbing, heating, compressed air, and general industrial systems. Its self-colour, natural iron finish offers a clean, unfussy look and can be painted or coated if needed. A hexagonal head allows straightforward tightening with a spanner. Ideal for trade, maintenance, and DIY tasks on pumps, manifolds, cylinders, and plant equipment. Manufacturer Part Number (MPN): 989 012.
Key Features:
- Durable malleable iron body for long service life and resistance to impact and thread wear
- 1/2" BSP female thread (approx. 12.7 mm / 1.27 cm) for broad compatibility with standard BSP fittings
- Hexagonal head for easy installation and removal using a standard spanner
- Self-colour finish that can be left as-is or painted/coated to suit the installation
- Reliable sealing of unused pipe stubs and ports when used with PTFE tape or suitable thread sealant
- Compact form factor for tight spaces and close-centre installations
- Helps maintain system integrity during commissioning, pressure testing, or temporary isolation
- Reusable component that can be refitted during maintenance or system changes
- Suitable for hot and cold water, heating circuits, and compressed air systems within typical service conditions
- Smooth, well-formed threads for consistent engagement and reduced risk of cross-threading
Typical Applications:
Capping pipe ends on plumbing and heating installations, sealing spare outlets on manifolds and valves, closing compressor and air line ports, protecting male BSP threads during storage or transport, isolating sections during maintenance, and blanking test points on pumps, tanks, and plant. Suitable for water, air, and compatible oils in workshops, factories, farms, and on-site setups.
