This sale is for 1 x Norma 4mm Inline Turbo Diesel Boost Gauge Damper for use when installing a mechanical boost gauge, these Inline dampers are used to cure the needle vibration associated with mechanical pressure gauges installed on turbocharged diesel engines. This is a high quality Norma inline hose joiner with an inbuilt brass restrictor so very simple construction and extremely easy to install. The inline damper simply fits inline on your pressure hose that goes direct to the back of your boost gauge. This inline damper will help reduce the infamous needle vibration on mechanical boost gauges and can also be used to stop unrestricted pressure from damaging internal diaphragms on expensive boost sensors if used with electrical gauges.

Please note that some cheaper/poor quality Chinese gauges may require further restriction to totally eliminate vibration, this is because of the low quality mechanisms used when manufacturing these cheap gauges. This product has been optimised specifically so that there is no detriment to gauge performance and various tests with recognised quality gauge brands have proven this product to be a must for any mechanical pressure gauge.

*This inline boost gauge damper is 4mm, there is also a 5mm boost gauge damper available to purchase in our other Ebay items.
