What is a CPVC 45° elbow?

IDMAR CPVC 45° elbow 1/2" glued system - hot water is a professional fitting for changing the direction of the pipeline by 45 degrees in domestic hot water installations, low-temperature heating and industrial systems.

Made of CPVC (chlorinated polyvinyl chloride), a material resistant to temperatures up to +80°C in continuous operation (with short-term peaks up to +90°C).

The 45° elbow allows for smoother changes in the direction of the pipeline than a standard 90° elbow, which translates into lower pressure losses, better flow and easier maintenance tight installation spaces.

The characteristic yellow color of CPVC makes it easier to identify the hot water system on the construction site and eliminates the risk of confusion with white PVC elements (cold water).

Technical parameters and dimensions

Dimension L (total length): | 17.8 mm

CPVC 45° 1/2" Elbow (code: CPVCKKW015XKW015-45.302) is an element enabling a gentle change of pipeline direction in hot water systems. Unlike 90° elbows, the 45° version ensures better water flow and lower pressure losses, which is particularly important in long installations or those requiring high efficiency.

The elbow has two glued sockets, which allows for easy and durable connection to CPVC pipes using a special glue. CPVC material resistant to temperatures up to +80°C is perfect for domestic hot water installations, underfloor heating and industrial applications.

Advantages of 45° elbows compared to 90°:

• Lower pressure losses: a smoother bend reduces flow resistance - ideal for long installations

• Better flow: smoother water movement, less turbulence, quieter operation of the installation

• Easier handling of tight spaces: two 45° elbows replace one 90° elbow and allow for greater routing flexibility

• Lower mechanical stress: a smoother transition reduces the risk of cracks due to thermal expansion

• Versatility: 45° and 90° elbows can be freely combined to obtain the optimal pipeline route.

Step-by-step assembly:

1. Cut the CPVC pipe with a saw or cutter at a right angle, remove burrs with a file or sandpaper.

2. Clean the surfaces of the connected elements with CPVC cleaner, wait until completely dry.

3. Apply CPVC adhesive evenly to the outside of the pipe and the inside of the elbow socket. We recommend Topterm CPVC 120 ml adhesive with a brush.

4. Insert the pipe into the elbow socket as far as it will go, rotate 1/4 turn, hold for 15 seconds.

5. Remove excess adhesive with a dry cloth. Wait 24 h at +20°C (or 48 h at temperatures below +10°C) before pressure testing.

⚠️ NOTE: PVC (cold water) and CPVC (hot water) elements ARE NOT INTERCHANGEABLE. PVC withstands a maximum of +20°C, CPVC – up to +80°C. Installing PVC in a hot water system may result in deformation, leaks and damage. Check the color: white = PVC (cold water), yellow/beige = CPVC (hot water).

Application CPVC 45° 1/2" elbow

• Domestic hot water (DHW) installations: pipeline routes in bathrooms, kitchens, boiler rooms

• Low-temperature heating systems: underfloor heating distribution, radiator connections

• Obstacle bypasses: bypassing beams, ventilation ducts, other installations

• Industrial installations: circulation process water, machine cooling, heat exchangers

• Swimming pools and SPA: water installations in technical rooms, connections of filters, pumps

• Modernizations: adapting existing installations to new space requirements

Frequently asked questions (FAQ)

What is the difference between a 45° and a 90° elbow?

A 45° elbow changes the direction of the pipeline by half the angle compared to a 90° elbow, which ensures lower pressure losses, better flow and quieter operation of the installation. Two 45° elbows can replace one 90° elbow, offering greater routing flexibility in tight spaces.

Can I use a CPVC elbow in cold water installations?

YES, the CPVC elbow also works perfectly in cold water (+1°C – +20°C), however, due to the higher price, we recommend it only for hot water installations. For cold water, choose a cheaper PVC elbow.

What is the maximum operating temperature of a CPVC elbow?

What glue should I use for installation?

We recommend certified glue for CPVC, e.g. Topterm CPVC 120 ml (with brush) available in our store. We also recommend using CPVC Cleaner 120 ml before gluing.

How long should I wait before starting the installation?

Is it suitable for drinking water?

YES, the CPVC elbow is suitable for drinking water installations.
