NNH Nozzle Coupling

Nozzle couplings (NNH) specially designed to attach the abrasive blasting nozzle to the blast hose. Lightweight, strong and durable, nozzle couplings are ideal for use in any type of compressed air blasting application.

Manufactured with hard injected nylon, the NNH nozzle couplings have 50mm thick threaded threads, which prevent nozzles from clogging due to the abrasive used. They have a high profile internal thread that facilitates assembly on the hose and prevents the couplings from inadvertently slipping off the hose.

All nozzle couplings are supplied with a rubber washer and a complete set of screws for fitting to the blast hose.

NHC Hose Coupling

Hose couplings (NHC) specially designed for attaching shot blast hoses to each other or to the pressure tank. Lightweight, strong and durable, hose couplings are ideal for use in any type of compressed air blasting application.

Made of hard injected nylon, NHC nozzle couplings are all identical, ensuring a perfect fit with each other. They have a high profile internal thread that facilitates mounting on the hose and prevents the couplings from inadvertently slipping off the hose.

They also have safety locking springs that automatically lock when two couplings are mounted together. The threaded equipment couplings (NTC) are threaded to attach to the dosing valve of the pressure tank.

Safety cable Hose / Hose

Safety cable to prevent damage and accidents in the event of coupling or blast hose failure. The safety cable must be installed on each hose connection and for safety reasons must be mounted extended.

Recommendations for use - Couplings

• Make sure that the abrasive hose you are using is made of premium quality virgin rubber inside and is designed to dissipate static build-up.
• The size of the hose must be appropriate for the specific blasting process to ensure that pressure loss is minimized and that the working pressure is optimum for the intended use.
• Use the blasting hose as straight as possible, avoiding sharp turns, kinks or kinks in the hose.
• Ensure that the couplings used are of the correct size and specification to match the outside diameter of the hose.
• Before assembling a coupling, make sure that the end of the hose is cut straight to ensure a perfect fit against the internal backing of the coupling. Make sure that when assembling the coupling, the hose is firmly pressed. In addition, Cym recommends the use of sealant on the end of the hose prior to fitting the coupling.
• The couplings are supplied with the corresponding screws to be properly attached to the hose. Use only the screws provided to avoid premature wear of the hose and nozzle coupling.
• Make sure that all nozzle couplings are equipped with a rubber washer and that the rubber washer is the correct size. The diameter of the rubber washer should match the inlet diameter of the blast nozzle being used.
• Make sure that all hose couplings are the correct size and that the safety springs are properly engaged. Inspect all coupling joints for air leaks and wear.
• Periodically inspect the condition of the couplings, the hose retaining bolts and the safety locking springs for any signs of wear or air leaks, and make sure that the coupling threads holding the nozzle are in good condition.
