## What radius can you bend PEX?

PEX Bend Support Bend supports generally bring the PEX to its tightest allowable 90-degree turn without folding or crimping. Turn radii differ according to PEX pipe diameter. For 1/2-inch PEX pipe, the tightest radius is usually 5 inches.

## Is PEX measured inside or outside diameter?

PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter).

**How much can PEX be bent?**

90° bends

PEX Bend Supports allow for 90° bends to be made with PEX tubing which can eliminate the need for additional fittings in certain instances, reducing the amount of potential leak points in a plumbing system. Bend supports also help to reduce noise and vibration.

**What is the outside diameter of 1/2 inch PEX?**

PEX Pipe Sizes and Dimensions –

PEX Tubing size (CTS/Nominal) | Outside Diameter (OD) | Volume gal/100ft |
---|---|---|

1/2″ | 0.625″ | 0.92 |

1″ | 1.125″ | 3.03 |

1 1/4 | 1.375 | 6.38 |

1 1/2 | 1.625 | 9.18 |

### What is the inside diameter of 1/2 inch PEX?

0.625

3) 5/8 in. tubing is better than 1/2 in. tubing.

3/8″ | 0.500 | 0.350 |

1/2″ | 0.625 | 0.475 |

5/8″ | 0.750 | 0.574 |

### How is bend radius measured?

The minimum bend radius formula is: L = A/360° x 2πr. Using this formula, the minimum required length of a hose can be determined for any situation. When calculating the length oa hose assembly, the length of the fittings must be considered.

**Is it better to bend PEX or use elbows?**

Use PEX bend supports instead of elbows. While these, unlike elbow fittings, cannot provide a sharp turn, they are suitable for most frame homes and will provide a certain degree of protection for the pipe from rigid/abrasive stud edges.

#### How do you calculate the radius of a pipe?

Divide the circumference of the pipe by π, which is a mathematical constant that begins with 3.14. For example, assume the circumference of the pipe is 60. Dividing 60 by π equals 19.099. Divide that number by 2 to calculate the radius.

**How do you find the bend angle?**

Input everything into the bend allowance formula: BA = angle × (π/180) × (radius + K-factor × thickness) .

**Will PEX elbows reduce flow?**

At a rate of 8 feet per second, the CPVC fitting will cause less than 1% restriction in flow while PEX fittings create a 23% to 54% reduction in flow, depending on the fitting used.

## Is PEX and copper same diameter?

While PEX tubing has a smaller inside diameter than copper tubing, both tubing systems meet the farthest fixture demand, even with multiple fixtures flowing.

## How do you measure bend radius?

**How do you measure pipe bends?**

Use the correct formula to calculate the circumference of the bend. For example, the formula used when making a 90˚ bend is: Circumference = (pi*2*r) / (360/90). When bending, take into account the ability of the material to bend and sustain the bend.
