100K 3/8" Plug

Stainless, 60° cone-seal plug for capping unused 3/8 inch high pressure ports in 94k/100k circuits (manifolds, crosses, tees, or head adapters). The precision cone mates to the port’s seat for a bubble-tight seal at full pressure, while the anti-vibration gland/collar pair holds preload under shock and motion. Ideal for isolating a branch, pressure testing, or parking a spare port without adding hose length.

• Insert Double Cone 3⁄8″ (012952-1) — renew the port’s seating faces (adapters/crosses) before installing the plug.
• 87K 3/8″ Cross w/o fittings (014168-1) — common junction where a branch may be capped with this plug.
  

Install tip: Clean and inspect the port seat; if it uses a replaceable insert, fit a new 012952-1. Torque the gland to spec and re-check after the first heat cycle to confirm a stable, leak-free seal.
