An RV propane regulator cover protects the correct part of a specific regulator—not every regulator with a similar metal housing. JR Products makes separate snap-on covers for vertical, horizontal and automatic changeover models, while Marshall Excelsior sells first-stage and second-stage cover pieces for selected two-stage assemblies. Use the model numbers and existing product photos below to identify which cover belongs to your regulator.
Three different JR Products cover arrangements
Begin with the exact label on your regulator. The manufacturer identifies one cover for each of these distinct regulator models:
Vertical regulator
Horizontal regulator
Auto changeover
Each of these covers is a separate part rather than a replacement gas-pressure regulator. Match the complete number on the existing regulator before ordering, and check that access and venting meet the exact manufacturer's instructions.
JR Products cover and regulator lookup
| Cover MPN | Manufacturer-matched regulator | Cover type |
|---|---|---|
| 07-30295 | 07-30365 | Vertical snap-on cover, one-piece plastic |
| 07-30305 | 07-30385 | Horizontal snap-on cover, one-piece plastic |
| 07-30315 | 07-30395 | Automatic changeover snap-on cover, one-piece plastic |
Marshall Excelsior first-stage versus second-stage covers
Marshall Excelsior uses different cover pieces for sections of its regulator assemblies. The MEGR-861 is listed as a first-stage cover for MEGR-291-series regulators. The MEGR-862 is the second-stage cover for compatible MEGR-253 and MEGR-291-series regulator configurations; MEGR-862P identifies a packaged version of the second-stage cover.
These are small regulator-cover parts, not the large plastic shell enclosing one or two full propane cylinders. The cover's physical profile and attachment points must match the part that is present, and an appropriate cover must never obstruct the regulator's vent.

These nine UsedRVParts listings show the cover pieces alongside the corresponding JR regulator models. Open the exact product page for its current price, availability and condition. Viewing or pickup, where offered, is by appointment in Kelowna.
Explore regulator and propane-system parts
If the regulator itself is damaged or an entire hose connection needs attention, use the appropriate regulator or component guide rather than choosing a protective cap as a replacement.
Manufacturer part matching references
JR Products explicitly documents the 07-30295 vertical cover, 07-30305 horizontal cover, and 07-30315 automatic-changeover cover. The Marshall Excelsior factory accessories reference separately identifies the MEGR-861 and MEGR-862 stage covers. Follow the specific regulator manual for approved orientation and safe gas-system service.
