300 and 400 Lever Bender Instruction Sheet

Inspection/Maintenance

The bender should be inspected before each use for wear or dam-

age that could affect safe use. Clean as needed to aid inspection

and to prevent handles and controls from slipping from your grip

during use.

Make sure the bender is complete and properly assembled. If any

problems are found, do not use until the problems are corrected.

Lubricate all moving parts/joints as needed with a light lubricating

oil, and wipe any excess oil from the bender.

Operation

The benders can be used either hand held or mounted in a vise. See

Figures 1 & 2 for area to be securely gripped in vise.

Spring Back

All tubing will spring back slightly after a bend is made. Amount

of spring back depends on tube characteristics. You may need to

slightly overbend the tube to compensate for spring back.

General Operation

1. Rotate the form handle and latch out of the way.

2. Position tube in form groove

and secure with the latch. At

least 1/8" (3 mm) of tube should

extend past the latch.

3. Rotate shoe insert into contact

with tube. Rotate the shoe

handle around the form until

the “0” line on the shoe insert

aligns with the desired degree

of bend on the form.

For 90° and 45° Bends:

Mark the tube at the desired distance (X) from the feature (end

of tube, bend, etc.). The center of the leg of the bend will be this

distance from the feature for 90° bends. The center of the arc will

be this distance from the feature for 45° bends.

Align the tube in the form.

a. For 90° Bends:

If the feature is to the of the mark, align the mark with the LEFT

90° line on the form.

If the feature is to the of the mark, align the mark with the RIGHT

R line on the form.

Instructions

WARNING

Read these instructions and the warn-

ings and instructions for all equipment

being used before using to reduce the

risk of serious personal injury.

• Always use safety glasses to reduce the risk of eye injury.

• Do not use handle extensions (such as a piece of pipe).

Selection of appropriate materials and installation, joining

and forming methods is the responsibility of the system designer

and/or installer. Selection of improper materials and methods could

cause system failure.

Stainless steel and other corrosion resistant materials can be con-

taminated during installation, joining and forming. This contamination

could cause corrosion and premature failure. Careful evaluation of

materials and methods for the specific service conditions, including

chemical and temperature, should be completed before any instal-

lation is attempted.

Description

The RIDGID® 300 and 400 Series Lever Benders are designed to

easily bend metal tubes to a maximum of 180°. The benders have

offset cushion grip handles and 90° start angle with specially de-

signed shoe to minimize bending efforts.

The 300 Series Plumbing benders are used to bend soft copper

tubes. The 400 Series Instrument benders can be used to bend

copper, steel and stainless steel tubes with a wall thickness up to

0.06" (1,5 mm).

See RIDGID catalog for specifications for each bender.

Double 45° Offset Bend:

1. Mark the tube at the desired distance (X) for the first 45° bend.

2. Multiply the offset dimension (Y) by 1.414 to get the centerline

dimension between the legs of the bend. Adjust the distance as

per bend adjustment chart.

Offset Leg Length = (1.414 * Y) – Bend Adjustment

3. Follow procedure for first 45° Bend.

4. Reposition the tube in bender for second 45° bend and make

the second bend.

Adjustment (Gain) Calculations

When determining tube bend locations, adjustment factors must be

considered to achieve proper layout. Adjustment (Gain) is the differ-

ence in the length of tubing used in a radiused bend compared to

the length of tubing required in a sharp bend, when measured from

one end to another.

The distance around a radiused bend is always less than a sharp

bend. The adjustment factor is determined by the radius of the tube

bender and the number of degrees of the bend. See the following

chart for ad justment factors. Adjustment factors are subtracted from

the center line distances (see the example).

* This product is dual purpose, being both inch and metric.

NOTE! Bend Adjustment (Gain) factors are calculated theoretical

values. Different types of tubing materials and wall thick-

nesses may require more or less adjustment.
