Product Description

Applications
 

ISO-KF fittings can be used in a wide variety of applications including:

• Roughing and foreline plumbing

• Small systems

• Systems requiring frequent cleaning or modification

• Research and teaching laboratories

ISO-KF components are primarily designed for use at

subatmospheric pressure.

Because of the large number of elastomer seals used.
 

Installation
 

The ISO-KF components are assembled by inserting a centering

ring between the two flange faces, then securing the assembly

with a flange encompassing clamp (see Figure 2).

ISO Flange Assembly Instructions

     Optional fastener flanges are joined around the periphery with clamps.
Double claw clamps are used when a pair of OF flanges are joined (See diagram A.),
or single claw clamps are used to join an OF flange to a tapped nonrotatable on a pump or gate valve. (See diagram B.)
This fastening method allows the OF flange to be rotateforease of component alignment. Additionally, a rotatable bolt ring can be
used to fasten an OF flange to a nonrotatable flange using bolts. (See diagram C.)
A retainer ring prevents the OF flange from slipping through the bolt ring. Nonrotatable ISO flanges are assembled with bolts.
(See diagram D.) They do not allow rotation of bolt holes on mating flanges to align components


CF FLANGE SERIES

CF flanges are available with tapped or untapped holes. Tapped flanges are available in UNC/UNF or metric threads. Tapped flanges
have through holes, so bolts may protrude slightly from the back of the flange when fastened to an untapped flange. Untapped CF
flanges can be fastened to each other with stainless steel bolts and hex nuts or plate nuts. Plate nuts center themselves over two
adjacent holes and can be held in place with one finger while the bolts are tightened. They are available for most flange sizes from 1 1/3
to 10 inch (33.96-254mm) ODs. As an alternative to hex head bolts, 12-point bolts are available for CF flanges from 2 3/4 to 10 inch
(33.96 to 354mm) ODs. Silver plated bolts eliminate the need for anti-seize compound in clean room environments.

Assembly Instructions for CF Flanges

1. Apply a small amount of high temperature anti-seize compound to the bolt threads.
2. Check that both flange surfaces are clean and sealing edges are free from nicks and scratches.
3. Using clean, lint free gloves, unpack gasket.
4. Place gasket in the knife edge counterbore of nonrotatable flange.
5. Align the mating hole pattern and leak test grooves.
6. Install the proper bolts and tighten hand tight. Check to see that the flange faces are parallel.
7. Tighten the bolts 1/4 to 1/2 turns using a star pattern until the flange faces are metal to metal.
8. Torque the fasteners to the listed value using the same pattern.
