In a regulated warehouse environment, Dresser gasket materials last up to 5 years. In the case of large sleeves and special fittings it is possible to have them refurbished at the factory to ensure they are in good condition when needed. Contact us to discuss a refurbishment program at your company.
After they have been installed, Dresser gaskets can become compressed to a new shape and may not be suitable for reuse. Likewise, after bolts and restraining rings have been subjected to stress under pressure they too may not be suitable. It is far safer to have new products available.
Chances are the expansion joint has not been maintained regularly. Call us for the Dresser maintenance recommendations.
This is largely a question of gas conditions. Our recommendation is always “If it is low top it up (slowly); if it is discolored replace it”. At the very least the oil should be replaced every five years.
The rotary meter body does not care what direction the gas is flowing, so the answer is yes. However, the index will react to the flow direction and may count forward or backward depending on its makeup. Contact us to look at the various options available to address this common challenge.
This happens a lot. Call us for the conversion table.
Depends on the meter size, but, in general, occasional over-speeding by 10% will not harm the meter. If you are constantly running the meter too fast you will accelerate the wear and tear on the meter. If that is the case it is much wiser to invest in a larger meter.
We have data sheets for each meter size. Contact us and let us know what you need. We will get you the correct information quickly

Sudden or severe on-off service can damage a rotary meter. We can supply an orifice restricting plate that will restrict the flow so that the meter cannot be over-sped. CONTACT US and request form RM-52 for the orifice plates available from Dresser. However, it is important to note that the orifice plates supplied from the factory are sized using the meter pressure rating and the maximum capacity of the meter. As a result, if your known flow conditions are less than those extremes the orifice may not be large enough. CONTACT US if you have any questions. We are happy to help!
First, you must have the following information before you start:
Once you have these requirements, you can proceed to the appropriate regulator spec sheet to size your regulator. We also have the on-line sizing tool to aid you in determining the correct type of regulator. Call us with any questions!
Gas coming out the vent of a regulator usually means debris has lodged between the valve seat & orifice not allowing the regulator to lock up. The easy fix for this is to remove the head from the valve body and clean the valve seat. If this does stop gas from leaking out of the vent, contact a factory representative for assistance.
Yes, all Roots regulators have threads in the vents for installing vent line. There are guidelines that must be followed when installing vent lines and these can be found in the Roots regulator spec sheets. Call us for help any time!
