Pipe fitting Onnline F-693365 15 mm hard

Onnline F-693365 15 mm hard pipe fitting is a rigid connector designed for mechanical joining of 15 mm diameter pipes in plumbing and heating systems. The fitting creates a stable, non-flexible connection suitable for fixed installations where dimensional stability and leak-free performance are needed. It is intended for use with compatible rigid pipe materials and standard 15 mm plumbing runs.

Advantages

The rigid construction ensures a secure mechanical joint that resists movement and maintains alignment of piping runs. Its compact 15 mm size makes it suitable for tight spaces and standard residential or light-commercial installations. The fitting is engineered for straightforward installation and long-term stability in water supply and central heating circuits, reducing the need for frequent adjustments.

Suitable for

• Domestic water supply lines with 15 mm rigid pipes
• Central heating circuits and radiator connections requiring non-flexible joints
• Fixed plumbing routes in kitchens, bathrooms, and utility rooms
• Repair or replacement of existing rigid 15 mm pipe connections

Key specifications

• Nominal pipe diameter: 15 mm
• Type: rigid/hard pipe fitting for mechanical connection
• Material: suitable for rigid plumbing materials (compatible with standard 15 mm rigid pipes)
• Application: water supply and central heating systems
• Connection characteristic: non-flexible, stable joint

How to use

Prepare the pipe ends by cutting them squarely and deburring to ensure full contact with the fitting. Insert the prepared 15 mm rigid pipes into the fitting until they reach the seat; ensure alignment and correct insertion depth. Secure the joint according to the compatible installation method for this type of rigid fitting (for example, mechanical compression or push-fit variant as applicable). After assembly, verify alignment and test the system for leaks following standard commissioning procedures.

Usage recommendations

Use with compatible 15 mm rigid pipe materials and follow local plumbing codes. Avoid using this rigid fitting in applications requiring flexibility or movement compensation. Pressure-test the assembled connection at recommended system pressures before final commissioning.
