ARAG G40004 Flat Gasket 1" (33×45×3 mm) — Silvan GG00002012
The genuine ARAG 1" flat sealing gasket — direct cross-reference to Silvan part GG00002012.
The ARAG G40004 is the same part as the Silvan GG00002012: a flat EPDM rubber gasket measuring 33 × 45 × 3 mm, made to seal 1" BSP ARAG and Silvan Selecta fittings. It's the standard seal behind 1" tank outlets, blanking caps, couplings and valve ports — and the first thing to swap when a fitting starts to weep under pressure.
Key features:
- Direct cross-reference — same part as Silvan GG00002012, identical fit and function
- Genuine EPDM rubber — 33 × 45 × 3 mm flat seal, resistant to ag-chemicals, UV and temperature extremes
- Suits 1" BSP fittings across the ARAG and Silvan Selecta ranges
- Replaces perished, flattened or lost seals — the most common cause of leaking outlets and blanked-off ports
- Genuine ARAG quality — the same gasket Silvan fits as original equipment
At this price, a fresh gasket beats chasing a chemical leak in the paddock — keep a few spares in the toolbox.
