QAre there any products such as lids to prevent foreign matter from entering into the KAMLOK couplings?
A

For each material, Dust Cap 634-B is available for couplers and Plug Cap 634-A for adapters.
However, they cannot be used in applications where pressure is applied or to prevent leakage. It is only for protection from dust and foreign matter.

QCan cam arms be replaced?
A

You can purchase a set containing a cam arm, pin and ring. Please let us know the material and size of your cam arm when ordering this.

QDoes KAMLOK have couplings with different diameters to reduce the size?
A

KAMLOK does not have couplings with different diameters.

There should be a method of adjusting and installing using general different-diameter bushings or the like in the thread part.

Q633-A, 633-F, 633-B and 633-D engraved on the KAMLOK body don’t have products with the same part number in the catalog or website. Are they discontinued?
A

These engravings are old type. The stamps are currently the same for those made of bronze.
The current product engravings and part numbers are as follows.

633-A, 633-F, 633-B and 633-D engraved on the KAMLOK body don't have products with the same part number in the catalog or website. Are they discontinued?

Connection

QIs the flange in the KAMLOK with Flange set compliant with JIS 10K?
A

Models such as the KAMLOK 633LAS and 633LBS have a flange that is compliant with JIS 10K.

QCan a 1/2″ coupler be connected to a 3/4″ adapter?
A

Yes, it can. The fitting areas of the 1/2″ coupler and 3/4″ adapter are the same size. Likewise, a 3/4″ coupler can be connected to a 1/2″ adapter.

QIs the KAMLOK compatible with lever type coupling made by other companies?
A

MIL standard lever type couplings and KAMLOK are compatible. However, the gasket specifications are different between companies. Our warranty only covers fittings and gaskets of the same manufacturer. Make sure that the size and material are the same.

QIs it okay to connect two KAMLOK made of different materials? For example, is it safe to connect an aluminum KAMLOK with a stainless steel one?
A

Connect with KAMLOK of the same material. Problems may occur due to electrical corrosion or wear.

QI tried to insert a KAMLOK hose shank into a common suction hose, but it was difficult. Is there a good way to insert it?
A

There are methods such as warming the hose insertion part with warm water and applying soap water to the hose shank. Also, it is possible to change the 633-CT coupler and 633-ET adapter with a slightly narrower hose shank.

Specifications

QWhat is the working temperature range of KAMLOK?
A

The working temperature range of KAMLOK depends on that of the gasket. With that said, the maximum working temperature for KAMLOK models made from polypropylene (PP) is 60°C.

QWhat is the working pressure range of KAMLOK?
A

It varies depending on the body material and size. Click here for reference information on working pressure ranges.
With that said, the working pressure of the hose needs to be taken into account when connecting the hose. Please also be aware that even if the pressure applied is within the working range of the hose, pressure may be released if depending on the clamps situation.

QHow do I attach the fall prevention chain (sold separately) to the KAMLOK 634-B (dust cap)?
A

Use the round connecting hole or the ring at the end of the arm.

QI would like to know the guideline for replacing the KAMLOK.
A

If the cam arm of the KAMLOK COUPLER feels loose or the liquid oozes, it is an indication to replace the gasket. If the cam arm feels loose even after replacing the gasket, it is due to wear, so replace it with a new KAMLOK adapter.

QWhat is the difference between KAMLOK 633-C and 633-CT, 633-E and 633-ET?
A

The difference between KAMLOK 633-C and 633-CT is the difference in the outer diameter of the shank where the hose is inserted. 633-CT is narrower than the 633-C and is used to be inserted into hoses that do not easily expand, such as suction hoses in general.
If the size does not match, fluid leakage or coupling disconnection may occur. The same applies to 633-E and 633-ET.
Use 633-E or 633-C for our hoses.

Gasket

QCan the gasket be replaced? Is it also possible to replace the gaskets specified at the time of purchase?
A

Gaskets are consumable items. They can be replaced by the customer.

It is also possible to replace with the gasket specified at the time of purchase. Specify when making order.

QI want to learn how to install the KAMLOK gasket. I’m trying to install a Teflon jacket gasket, but it’s tight on the side. Is it safe to push it in?
A

Forcibly inserting it may cause streaks and deformation in the Teflon part, which may cause leakage.
To install the gasket, immerse it in hot water at 80℃ for 10-15 seconds (increasing flexibility) and firmly insert the gasket diagonally along the streaks (including the filler part).
When purchasing a new product, gasket replacement can also be provided, so consult with the supplier.
