Rubber Grommets For Refrigeration pipe

For sale! Compressor rubber Grommets for  refrigerant compressor copper tube 1/4″,3/8″,1/2″,5/8″,3/4″, 1inch…,Refrigeration copper pipe rubber add-on weight block.

The rubber grommets is used as counterweight for compressor copper pipe system,including HVAC compressor of air conditioner,freezer,fridge and heat pimp.In the refrigeration pipe system,engineer always use these rubber blocks to adjust the natural frequency of the refrigerant pipe,noise and vibration by changing the weight of the refrigerant pipe of the air conditioner, and so to avoid the resonance of the refrigerant pipe. The natural frequencies of different air conditioner pipes are different and therefore the weight of the rubber grommet must be matched with it. There are many sizes of refrigerant pipes for  many compressors in the HVAC system, but fewer types of counterweights can be find in market,and thus,Smartclima make many moulds to develop most of counterweight grommets (rubber add-on weight block) to adapte to the refrigerant pipe structure of different refrigerant pipes.
These parts are the best choice for your refrigerant compressor to remove noise and vibration.


  • [Material and Description] These Rubber Compressor Grommets For HVAC project are made of high quality rubber,anti-aged performance, and they are always used to reduce or remove vibration or working noise which comes from compressor installed in freezers,refrigerators,air conditioner outdoor unit and heat pumps.

General knowledge for “Rubber Grommets For Refrigeration pipe.rubber add-on weight block ”

The air conditioning or refrigeration system copper pipeline inevitably will generate vibration when the compressor is running, especially the exhaust pipe and the suction pipe directly connected to the compressor. Conventional practice is to change the resonant frequency by adding rubber eccentric weights or Rubber Grommets(names rubber adding weight) onto the copper tube. Another method is to absorb the vibration by wrapping the copper tube with the rubber piece(also names Air Conditioning Pipe Fittings Rubber Clump Weight), and also has the function of  add-weight.

The main material of the clay(Air Conditioning Pipe Fittings Rubber Clump Weight) is butyl rubber, which is made with other environmentally-friendly additives. It is a self-adhesive self-adhesive damping rubber sheet made by advanced technology. It adopts anti-adhesive paper layer and is covered with transparent film. It has strong adhesion to various materials, and has excellent weather resistance, aging resistance and water resistance. It seals and absorbs the surface of the adherend. , protection and other functions.
Recently, some of the rubber purchased on the market has been found to be tied to the exhaust pipe. The time is not long, the material melts and falls off from the copper tube, thus losing the shock absorption effect. After analysis and inquiry, some air conditioner manufacturers have technical requirements for the damping block. It is found that the cement needs to meet the test requirements of weather resistance, heat resistance, high temperature fluidity, low temperature flexibility, copper tube corrosion and toxicity. Be sure to test or purchase qualified products from air-conditioner manufacturers. You can’t buy goods or small workshops. The small details will affect the quality of the products.
The brief requirements are as follows:
Heat resistance and cold resistance  
1.1 High temperature resistant damping damping block, required to test at -20 ° C ± 5 ° C and 115 ° C ± 5 ° C temperature for 72 hours, no flow, no hardening.  
1.2 Low temperature resistant damping damping block, required to test at -40 ° C ± 5 ° C and 50 ° C ± 5 ° C temperature for 72 hours, no flow, no folding without cracking. 
2. Metal corrosive   damping damping block has no corrosive effect on metallic copper, iron and surface coating (test temperature 100 ° C, time 7 days).
3. Toxicity and odor   damping The damping block is required to be non-toxic and odor-free (distilled water is colorless, odorless, non-toxic after being placed in 40 distilled water for 24 hours). 
4. The service life   damping damping block can be firmly pasted, and there is no phenomenon of runny, shedding, hardening, brittleness, cracking and the like during the use period.
