Suburban Furnace Electrode Gasket | 525011 | NT & P Series

Restore a proper seal at your Suburban RV furnace electrode and burner door with the Suburban 525011 OEM Electrode Gasket. This genuine Suburban replacement gasket seals the electrode penetration AND the burner door — both critical sealing points that prevent combustion gas leaks, exhaust escape, and air infiltration that can affect furnace performance and safety. A small part with a meaningful safety job.

What This Gasket Does

The 525011 serves a dual sealing function:

• Electrode gasket — seals around the igniter electrode where it passes through the furnace housing
• Burner door gasket — seals the burner access door when closed

Both sealing surfaces are critical for proper furnace operation. A failed gasket can cause:

• Combustion gas leakage into the RV interior
• Air infiltration that disrupts proper air/fuel mixing at the burner
• Reduced combustion efficiency
• Potential safety risks from improper combustion sealing

Wide NT and P Series Compatibility

The 525011 fits an extensive range of Suburban NT Series and P Series furnaces:

NT Series (small furnaces — 12K to 20K BTU)

• NT-12 variants: NT-12L, NT-12LE, NT-12LEC, NT-12S, NT-12SE
• NT-16 variants: NT-16L, NT-16LE, NT-16LEC, NT-16S, NT-16SE, NT-16SEQ, NT-16SQ
• NT-20 variants: NT-20L, NT-20LE, NT-20S, NT-20SE, NT-20SEQ, NT-20SQ, NT-20T

NT Series (mid-size furnaces — 24K to 34K BTU)

• NT-24 variants: NT-24M, NT-24S, NT-24SP
• NT-25K
• NT-30 variants: NT-30K, NT-30M, NT-30S, NT-30SP
• NT-34 variants: NT-34L, NT-34S, NT-34SP

NT Series (larger furnaces — 35K to 45K BTU)

• NT-35K
• NT-40
• NT-42T
• NT-45S

P Series

• P-30S
• P-40
• P-40B
• P-40S

That's broad coverage across the Suburban NT and P furnace lineup — making the 525011 the right gasket for most NT/P series electrode and burner door sealing needs.

Cross-Reference Part Numbers

The 525011 is the direct replacement for two earlier Suburban part numbers:

• Replaces 071076
• Replaces 072102

If your existing gasket shows either of those part numbers, this 525011 is the current production successor.

When to Replace the Gasket

Common reasons to replace the electrode/burner door gasket include:

• Visible deterioration, cracking, or breakdown of the existing gasket material
• Loss of resilience — gasket no longer compresses and seals properly
• Gas smell around the furnace cabinet during operation
• Performing other furnace service — gasket replacement is cheap insurance whenever the burner door is opened
• Furnace efficiency or operation problems that may be caused by air infiltration

Gaskets are typically replaced alongside other furnace service work — whenever you're opening the burner door or replacing the igniter electrode, swapping the gasket is straightforward and inexpensive insurance.

Genuine Suburban OEM Replacement

As a Suburban factory replacement part, the 525011 is built to original specifications for a precise drop-in fit in compatible NT and P series furnace installations.

⚠️ Professional Installation Recommended

Furnace component replacement should be performed by a qualified RV service technician. While gasket replacement itself is straightforward, working inside the furnace cabinet near the combustion chamber and gas valve requires care — and a professional service tech can verify proper gas-tight sealing after installation.
