Mega O-Ring for Low Speed Needle (6)
MEG202073
Pack of six precision rubber O-rings for the low-speed needle valve on Mega ZX12/15/21 DSII+ RC nitro engines (MEG202073), ensuring leak-free sealing and smooth idle mixture adjustment for stable low-RPM performance.
Maintain flawless idle and transition tuning with this official 6-pack of low-speed needle O-rings (MEG202073) for Serpent Mega ZX12, ZX15, and ZX21 DSII+ nitro engines. Manufactured from fuel-resistant, high-durometer rubber, these seals prevent vacuum leaks around the low-speed needle shaft, preserving consistent air-fuel mixture at idle and off-throttle—critical for clean launches and corner exits in 1/10-scale off-road and on-road racing. Easy to replace during routine carb servicing or full engine rebuilds, they restore precise needle control and eliminate lean stumbles caused by aged or swollen seals. Stock up with this value pack to keep your Mega nitro engine responsive and race-ready, lap after lap, without tuning headaches.
