B. Deburring

Use a knife, plastic pipe deburring tool, or ﬁ le to remove burrs from

the end of small diameter pipe. Be sure to remove all burrs from

around the inside as well as the outside of the pipe. A slight chamfer

(bevel) of about 10°-15° should be added to the end to permit easier

insertion of the pipe into the end of the ﬁ tting. Failure to chamfer the

edge of the pipe may remove cement from the ﬁ tting socket, causing

the joint to leak.

STEP B

C. Test dry ﬁ t of the joint

Tapered ﬁ tting sockets are designed so that an interfaced ﬁ t should

occur when the pipe is inserted about 1/3 to 2/3 of the way into the

socket. Occasionally, when pipe ﬁ tting dimensions are at the tolerance

extremes, it will be possible to fully insert dry pipe to the bottom of

the ﬁ tting socket. When this happens, a sufﬁ cient quantity of cement

must be applied to the joint to ﬁ ll the gap between the pipe and ﬁ tting.

The gap must be ﬁ lled to obtain a strong, leak-free joint.

D. Inspection, cleaning, priming

Visually inspect the inside of the pipe and ﬁ tting sockets and remove

all dirt, grease or moisture with a clean dry rag. If wiping fails to clean

the surfaces, a chemical cleaner must be used. Check for possible

damage such as splits or cracks and replace if necessary.

Depth-of-entry

Marking the depth of entry is a way to check if the pipe has reached

the bottom of the ﬁ tting socket in Step F. Measure the ﬁ tting depth

and mark this distance on the pipe O.D. You may want to add several

inches to the distance and make a second mark as the primer and

cement will most likely destroy your ﬁ rst one.

Apply primer to the surface of the pipe and ﬁ tting socket with a natural

bristle brush. This process softens and prepares the PVC or CPVC

for the solvent cementing step. Move quickly and without hesitation

to the cementing procedure while the surfaces are still wet with

primer.

E. Application of solvent cement

• Apply the solvent cement evenly and quickly around the outside

of the pipe at a width a little greater than the depth of the ﬁ tting

socket.

• Apply a light coat of cement evenly around the inside of the

ﬁ tting socket. Avoid puddling.

• Apply a second coat of cement to the pipe end.

STEP E

F. Joint assembly

Working quickly, insert the pipe into the ﬁ tting socket bottom and

give the pipe or ﬁ tting a 1/4 turn to evenly distribute the cement. Do

not continue to rotate the pipe after it has hit the bottom of the ﬁ tting

socket. A good joint will have sufﬁ cient cement to make a bead all

the way around the outside of the ﬁ tting hub. The ﬁ tting will have a

tendency to slide back while the cement is still wet so hold the joint

together for about 15 seconds.

STEP F

G. Cleanup and joint movement

Remove all excess cement from around the pipe and ﬁ tting with a

dry cotton rag. This must be done while the cement is still soft.

The joint should not be disturbed immediately after the cementing

procedure, and sufﬁ cient time should be allowed for proper curing of

the joint. Exact drying time is difﬁ cult to predict because it depends

on variables such as temperature, humidity and cement integrity. For

more speciﬁ c information, you should contact your solvent cement

manufacturer.
