Quick Trade Summary: Brass Compression Female Iron 90° Elbow
MEP Stock supplies heavy-duty forged brass compression female iron (FI) 90-degree elbows engineered for tight directional transitions from copper tube to male-threaded plant, radiator tails, and boiler components. Manufactured to BS EN 1254-2 with high-strength CW617N brass.
Precision 90° Directional Transitions for Threaded Component Feeds
Connecting compact 10mm microbore or 15mm/22mm copper pipework into male-threaded water heaters, pressure vessels, heating valves, and oil/radiator components requires rigid 90-degree geometry. Our compression FI elbows deliver robust angular transitions without putting rotational or shear stress on copper joints.
Engineering Specifications
| Body Material | High-Grade Forged CW617N Brass (BS EN 1254-2) |
| Inlet Connection | Compression Nut & Brass Olive for Copper Tube (10mm to 22mm) |
| Outlet Connection | Internal Parallel Female BSP Thread (3/8" to 3/4" FI BSP) |
| Operating Pressure | 16 bar at 30°C / 10 bar at 65°C / 6 bar at 110°C |
| Temperature Range | -10°C to +110°C |
| Application | Radiator Connections, Microbore Systems, Boiler Feeds, Water Changers |
BS EN Installation Protocol
- Step 1: Thread Seal Male Pipe — Apply 4 to 6 wraps of PTFE tape clockwise onto the male mating thread.
- Step 2: Tighten Threaded Elbow End — Screw female elbow onto male fitting, orienting the compression socket toward incoming pipe.
- Step 3: Cut Copper Tube Square — Cut copper tube square, deburr completely, and slide nut and olive onto pipe.
- Step 4: Seat Pipe in Socket — Push copper tube firmly into compression socket until it touches internal shoulder.
- Step 5: Tighten Compression Nut — Hold elbow body firmly with spanner and tighten compression nut 3/4 to 1 turn past hand-tight.
Frequently Asked Questions
What applications use 10mm x 3/8" or 15mm x 1/2" FI elbows?
Commonly used on microbore heating systems, fan coils, and compact boiler connections.
Commonly used on microbore heating systems, fan coil units, water chillers, and compact boiler connections where male threaded tails enter perpendicular to wall runs.
How do I ensure the elbow points in the correct direction when tightening?
Count turns and snug the joint when the socket aligns directly with the pipe run.
Count turns and snug the joint when the socket aligns directly with the pipe run. Use a quality thread sealing compound or PTFE tape to allow final angular alignment without over-torquing.
Can I use this fitting on soft copper coil?
Yes, provided internal brass tube support sleeves (liners) are fitted inside soft copper.
Yes, provided internal brass tube support sleeves (liners) are fitted inside soft annealed copper (R220) to prevent olive crimp collapse.
Is this elbow certified for potable drinking water?
Yes, forged from high-purity brass compliant with BS EN 1254-2.
Yes, forged from high-purity brass compliant with BS EN 1254-2 for hot and cold wholesome drinking water.
Can I use jointing paste on the olive?
A light smear of non-setting paste is permitted but not required on clean cuts.
A light smear of non-setting paste is permitted on the olive taper, but never use paste on the female internal threads.
What size variations are stocked?
Stocked from 10mm x 3/8" FI up to 22mm x 3/4" FI BSP in single pieces and bulk packs.
