Choosing a 135-degree silicone elbow

Match the specified internal diameter to the outside diameter of your connecting pipework. Check both end sizes, leg lengths, bend dimensions and installation clearance before ordering. Select clamps suitable for the hose's outside diameter.

Confirm the manufacturer's operating temperature, working pressure and fluid compatibility for the exact part before use. A burst-pressure figure is not a working-pressure rating. For heating or cooling installations, confirm suitability for the intended fluid and operating conditions.
