- Compatible with the MRS regulator only, and intended for use of systems capable of operating at 145 PSI
- Simple installation into MRS Regulator system
- Safely increase pressure ratings without the need to shim any components
Looking to get a little more "ooph" out of your MRS regulator? Well then you are in luck since this beefy spring will do just that. Changing out the spring can be done in a matter of minutes and will safely increase the output of your regulator to ~200psi while still retaining the ability to operate at 40psi.
Although some pressure gains can also be accomplished by shimming the original spring, changing the spring is more beneficial than the typical shim method. When a spring is shimmed, the whole pressure range shifts up so you lose your low end pressure range. By simply changing the spring's rate, the regulator still has the ability to operate at 40psi. Even though the high pressure spring will technically not allow the regulator to recharge quite as quickly at that low pressure in comparison to the standard spring, at conservative rates of fire it is not going to be noticeable.
