Multi-Layer Transit Seals
Modular cable and pipe transits for walls, floors, bulkheads and decks. Peel-to-fit rubber modules seal any cable diameter in their range, frames weld, bolt or cast in, and the assembly holds back fire, water, gas, dust and rodents — with spare capacity built in for the next upgrade.
Exclusive international partner. Outside China, this transit-sealing system — proven on metro, power-grid and data-centre projects — is supplied, engineered and supported only through Prestige Industrial.
Peel-to-Fit Sealing Modules (HM & BM)
The heart of the system: split, halogen-free EPDM modules with a peelable multi-layer core. Peel layers until the module grips the cable — no measuring, no module per cable size, far less stock. Solid-core modules double as blanks for spare capacity. HM modules are 60 mm deep, BM 30 mm.

Weld-In Rectangular Frames (PT & PTH)
Steel frames welded into bulkheads, decks and cabinet walls — from a single 60 × 60 mm opening up to nine 120 × 120 mm openings side by side. PTH frames add 20 mm corner radii to spread stress in load-bearing structures.
- PT series 1x1 → 4x9 · 1–9 openings · 121×80 → 180×1185 mm
- PTH r20 series 2x1 → 6x3 · openings up to 180 × 120 mm · radiused
- Material Low-carbon steel · 60 mm deep · weld-in
- Rated pressure 4 bar water · 2.5 bar gas
Bolt-On, Cast-In & Roof Frames (ZH · PTE · SN)
For where welding isn’t an option. ZH flanged frames bolt on or cast into concrete and build up from modular sides to the size you need; PTE gooseneck frames bring cables in through roofs; SN lightweight composite frames bolt on and open to fit around existing cables.
- ZH frame kits Galvanised steel · modular sides 60–240 mm · bolt-on or cast-in
- PTE gooseneck 6x1 / 6x2 · 180 × 120 mm openings · roof entry
- SN composite frame 6x1 · 180 × 120 mm · with or without flange · IP66/67
Retrofit Frames & Kits (ZHN · ZHX)
Seal around cables that are already installed. ZHN composite frames assemble from side and mid sections into one-, two- or three-opening frames; ZHX aluminium kits bolt together around live cable runs with compression built in, supplied complete with adjustable modules.
- ZHN composite PA6 + 30% GF · 6x1 → 6x3 · bolt or rivet · IP54
- ZHX 24 kits 8, 12 or 28 cables · Ø3.5–32.5 mm · IP67
- ZHX frame Aluminium · 209 × 100 × 30 mm · M6 bolts
Round Transit Seals (Y & RY)
For core-drilled holes and sleeves. Y frames expand inside a round hole and hold a square pack of HM modules for several cables; RY seals are two peelable half-rounds with stainless end plates and integral compression for a single cable or pipe — fitted around existing runs with no disconnection.
- Y 100 → Y 200 Ø100–202 mm holes · 60×60 → 120×120 mm module space
- RY 25 → RY 125 (centre plug) Ø25–127 mm holes · cable / pipe Ø3.6–98 mm
- RY 100 → RY 644 Ø100–647 mm holes · cable / pipe Ø48–580 mm
- Sleeves (GT / GTF) Steel, plain or flanged · Ø83–658 mm OD
Compression Wedges & Accessories
Bolt-tightened wedge units compress the module pack inside PT, PTH and ZH frames; stayplates lock each row so cables can’t be pulled through; wedge blocks suit frames without built-in compression. Assembly lubricant completes the kit.
- Wedge units YJH 60 / YJH 120 · bolt-tightened
- Stayplates GB 120 · between rows, stop cable pull-out
- Assembly lubricant Eases module fit-up
