TECHNICAL SPECIFICATIONS & CONSTRUCTION

Description & Operational Features

Test-Tite Single size Bypass Plug is engineered for versatile, fail-safe flow isolation across civil, municipal, and industrial pipelines. Constructed with multi-layer natural rubber and high-tensile Kevlar cord reinforcement, it accommodates wide variations in pipe diameters while maintaining exceptional airtight and watertight seal integrity under demanding back-pressure.

KEY PERFORMANCE ATTRIBUTES

◆

NR + Kevlar Reinforcement Matrix: Constructed from premium vulcanised natural rubber (NR) reinforced with multiple plies of Kevlar aramid cord, offering extreme puncture resistance, ozone stability, and temperature tolerance from -40°C to +70°C.

◆

High Back-Pressure Sealing Hold: Engineered contact profile creates circumferential friction sealing that securely withstands high back pressure in clean, clay, PVC, ductile iron, and concrete pipelines.

◆

Multi-Size Dynamic Expansion Range: Elastomeric memory allows single plugs to seal across diverse standard nominal diameters, dramatically reducing fleet inventory requirements for civil drainage contractors.

◆

Heavy-Duty Anti-Slip Circumferential Ribs: Moulded non-slip ridges bite securely against wet pipe inverts and biofilm without causing surface abrasion to pipe lining.

◆

Certified Schrader & Quick-Coupler Air Connection: Equipped with heavy-duty brass inflation valve compatible with standard mobile compressors, hand pumps, and safety relief controller hoses.

FIELD DEPLOYMENT PROTOCOL

Step-by-Step Operating & Safety Guidelines

Pipe Bore Inspection

Inspect pipe interior and remove sharp gravel, protruding taps, or metal burrs that could compromise the rubber body.

Tether Anchoring

Always connect a certified safety steel tether or retrieval rope to the eyebolt and secure to an external trench shoring anchor.

Controlled Inflation

Inflate slowly using a calibrated pressure controller with a relief valve. Never exceed the rated bar on the product nameplate.

Depressurise & Extract

Release upstream back-pressure completely before venting plug air. Once deflated, pull gently by the tether—never pull by inflation hoses.
