Description
Overview:
The Blanking Cap 3/4" BSP Malleable is a threaded pipe closure used to seal the end of BSP pipework and fittings to prevent leaks and protect system integrity. Made from robust malleable iron, it combines strength with a degree of ductility, helping it withstand tightening loads and everyday knocks without cracking. The cap features a 3/4 inch BSP female thread, suitable for standard BSP installations on site and in the workshop. For reference, 3/4 inch is nominally 19.05 mm, while the BSP thread outside diameter it mates to is approximately 26.4 mm. Typical uses include capping off open ports on manifolds, pumps and air or water lines in construction, agricultural and garden machinery support systems. Manufacturer Part Number: 989 034.
Key Features:
- 3/4" BSP female thread for standard pipework (approx. 26.4 mm thread OD; nominal 19.05 mm size)
- Malleable iron construction for durability and resistance to impact and thread stress
- External spanner flats for easy tightening and removal in tight spaces
- Provides a secure seal to prevent leaks and protect open ports during use or storage
- Suitable for temporary or permanent closures in maintenance, commissioning and pressure checks (use with appropriate thread sealant)
- Reusable component; simply clean the threads and refit with fresh PTFE tape or pipe sealant
- Consistent fit with BSP threads found in general plumbing, site services and workshop systems
- Compact form factor keeps assemblies neat and reduces snagging risks
Typical Applications:
Sealing off unused or spare 3/4" BSP ports on pipe manifolds, pumps, valves and tanks; isolating sections of water or air lines during repairs; providing a safe, temporary closure for pressure testing at appropriate levels; protecting threaded connections from dirt and damage during transport or storage on site and in workshops.
Also known as:
Pipe end cap, female BSP cap, threaded blanking cap, BSP stop end, screw cap, closure cap, sealing cap, pipe terminator, pipe closure, BSP female stop.
