Order factory-direct from 1×20ft container, or take a LCL from our Turkey ready stock — no full container needed. OEM / private-label available. Afghan factory since 2020 · production up to 80,000 rolls/day · exporting across the Gulf, MENA & Central Asia · Turkey stock · 12mm & 19mm · 250/200 per carton · quality-controlled full-density tape.
High density PTFE tape bulk supply from Gram Tape is engineered for industrial and high-pressure pipe applications where standard plumbing-grade tape is not sufficient.
High density PTFE tape is engineered for industrial and high-pressure applications where standard plumbing-grade tape is insufficient. With a density of 0.55 g/cm³ and above, high density thread seal tape delivers a tighter, more resilient thread fill that holds up to steam, chemicals, hydraulic pressure, and thermal cycling. Gram Tape manufactures high density PTFE tape and supplies it in wholesale quantities to industrial distributors, MRO suppliers, and OEM manufacturers worldwide.
What Makes High Density PTFE Tape Different?
Minimum order — export
12mm — 37,500 pcs (150 cartons) · 19mm — 12,000 pcs (60 cartons)
Shipped LCL from our Türkiye depot, so no full container is required. OEM and private label start at 1 × 20ft container factory-direct from Herat. Carton packing is 250 pcs (12mm) and 200 pcs (19mm).
Standard PTFE thread seal tape is manufactured at low densities (0.20–0.35 g/cm³) to keep costs low and make the tape easy to tear by hand. This is entirely adequate for household plumbing. High density PTFE tape uses more PTFE material per roll, creating a film that is heavier, thicker per wrap, and more compressible under assembly torque. The result is a more complete seal with fewer wraps required and better performance in demanding environments.
Density Guide: Matching the Grade to the Application
| Density Range | Grade | Typical Applications |
|---|---|---|
| 0.20 – 0.35 g/cm³ | Standard | Household water supply, cold water plumbing |
| 0.40 – 0.55 g/cm³ | Medium | Hot water, steam, light industrial |
| 0.55 – 0.75 g/cm³ | High Density | Gas lines, hydraulics, chemical process |
| 0.80 – 1.00+ g/cm³ | Ultra-High | Defence, aerospace, aggressive chemical duty |
