METAGLAS® Type 64 — Round Head Threaded Sight Glass (Flush-Mount, Oil Level)

The METAGLAS® Type 64 Round Head is a flush-mounted, air-side threaded sight glass engineered for female metric or Whitworth (BSPP/BSPT) connections. Purpose-built for oil level indication, the low-profile round head delivers maximum visibility with minimal protrusion — clean, safe, and production-ready.

Design & Construction

  • Interface: Female metric or Whitworth (BSPP/BSPT) thread
  • Mounting: Flush-mounted on air side — round head, low build height
  • Optics: METAGLAS® metal-fused sight glass — permanent compressive pre-stress for fail-safe integrity
  • Body: Corrosion-resistant stainless steel (other alloys on request)
  • Sealing: O-ring or flat gasket options to suit media, pressure, and temperature
  • Duty Envelope: Pressure/temperature dependent on size and materials (provided at quote)

Applications

  • Gearboxes, reservoirs, and pump housings — oil level & condition monitoring
  • Hydraulic power units and lubrication skids
  • General machinery inspection ports where snag-free, flush optics are required
  • Utilities and process equipment — water/coolant/non-aggressive media
Key Advantages:
  • Flush round head = snag-resistant, easy-clean, operator-safe
  • Metal-fused glass = no delamination, no creep, no surprises
  • Shock, vibration, and thermal-cycling resilient — built for uptime
  • Rapid retrofit via standard metric/BSP threads
  • Compact footprint with maximum viewing aperture

Ordering Checklist

  • Thread type & size (Metric / BSPP / BSPT)
  • Pressure & temperature envelope
  • Medium (oil type/viscosity, cleanliness requirements)
  • Body material & surface finish
  • Seal type/material (NBR, FKM/Viton®, EPDM, etc.)
