Rubber grommets for compressor refrigeration pipe,heat pump compressor copper pipe rubber grommet parts,rubber weight add-on sleeve blocks are on sale.Fit for heat pump`s compressor copper tube size1/4″,3/8″,1/2″,5/8″,3/4″, 1 inch…

The rubber grommets is used as counterweight for compressor copper pipe system,and so, it it also named refrigeration copper pipe rubber add-on weight blocks,rubber sleeve.In the refrigeration pipe system or heat pump system,engineer always use these rubber blocks to adjust the natural frequency of the refrigerant pipe,to reduce,absorb or remove 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 from different refrigeration pipe system are different and therefore the weight of the rubber grommet must be matched with system. 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 the compressor in HVAC system, air conditioner,freezer,fridge and heat pimp to remove noise and vibration.

Compressor copper pipe system rubber grommets are specifically designed to absorb and remove the resonance sympathetic vibration from the compressors in HVAC Refrigeration system,and thus become the top-quality vibration isolation and dampening choice for copper tube when refrigeration compressor working.

Advantage :

√ Made from natural rubber,can stand high temperature,can stand long years and anti-aged,use antiaginy technology.
√ High in strength,and no easy to break;
√ Easy to use,just around the copper tube and tie it;
√ Various types and various sizes to meet your demand;
√ Customizable size if you required.


[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. The working principle is to mount copper pipe( suction & discharge line from compressor) and thus avoid or reduce viberation from the HVAC system. And so,they are also named with rubber vibration dampening grommets,Rubber buffer kits,rubber antivibration blocks or adding weight for refrigeration copper pipe system. 

[Models and Available Size] For  refrigerant copper tube 1/4″,3/8″,1/2″,5/8″,3/4″, 1inch…(See below tables).

[Feature] Abrasion resistant;High in strength;Perfect finish.

[Application] This rubber sleeve is always used in refrigeration HVAC system,including air conditioner, heat pump water heater, air dehumidifier,fridge,ice machine,etc,to mount on the copper pipe and thus to avoid or reduce viberation from the system.

[Customized Design] For special dimension, accept customized production if bulk order.

Application of Rubber Split Grommets Rubber Weights:
This product is always used in HVAC refrigeration system,to mount compressor`s copper pipe system and thus to avoid or reduce viberation from the HVAC system working.Made from qyality rubber,anti-aged performance.

Method of use:
Because the rubber grommet is to prevent collisions between the pipes, due to the eccentric protection pipe plastic piece of ontology, to ensure that the assembly location accurate, usually to protect pipe rubber block position remains unchanged, with a corresponding tighten belt tied tightly.

Some knowledge for “Rubber Grommets For Compressor 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 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, we found some low-quality gromments made of bad rubber which will melt and fall off from the copper tube, thus losing the shock absorption effect. All air conditioner and heat pump manufacturers have technical requirements for the damping block as following that the grommets needs to meet the test requirements of weather resistance, heat resistance, high temperature fluidity, low temperature flexibility, copper tube corrosion and toxicity. sure to test or purchase qualified products from top quality rubber manufacturers. You can’t buy goods or small workshops. The small details will affect the quality of the whole air conditioner system.
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 of damping block can be firmly tied or pasted, and there is no phenomenon of runny, shedding, hardening, brittleness, cracking and the like during the using period.
