Heat-Shrink Welding Sleeve PPRC-45×P100, No name (MPN PPRC-45*P100)

Heat-Shrink Welding Sleeve PPRC-45×P100 is designed for insulation and mechanical protection of pipeline and cable joints. The sleeve is made to shrink when heated, creating a tight, conforming barrier around fittings and welded joints. It is suitable for use with PPRC (polypropylene random copolymer) piping systems to protect connections from moisture ingress and mechanical wear during installation and operation.

Advantages

The heat-shrink sleeve provides reliable sealing by contracting uniformly when exposed to heat, which helps to reduce the risk of leaks and corrosion at joints. Its construction offers mechanical reinforcement around welded areas, improving resistance to abrasion and external impact. The product is straightforward to apply and compatible with common piping repair workflows, making it practical for both new installations and on-site repairs.

Suitable for

• Insulation and protection of PPRC pipe welds and fittings
• Repairing damaged or leaking joints in plumbing systems
• Mechanical reinforcement of pipeline connections exposed to wear
• Protection of cable or small-diameter pipe splices in damp environments

Key specifications

• Intended shrink application: tubular sleeve for welded joints and fittings
• Nominal pre-shrink dimensions: 45 mm diameter × 100 mm length before heating
• Material compatibility: designed for use with polypropylene copolymer piping and similar thermoplastic surfaces
• Primary function: thermal shrink-to-fit sealing and mechanical protection
• Typical operating environment: plumbing and pipe assembly, indoor and sheltered outdoor use where moisture protection is required

How to use

Prepare the joint area by cleaning and drying the surfaces to be covered. Slide the sleeve over the fitting or welded joint so it is centered on the area requiring protection. Apply controlled heat using an appropriate heat gun, moving evenly around the sleeve until it uniformly contracts and adheres to the substrate, forming a tight seal. Allow the sleeve to cool and verify the shrink has fully conformed to the joint before returning the system to service.

Usage recommendations

Use a regulated heat source and maintain safe distances to avoid overheating adjacent pipe material. Ensure surfaces are free from oils, dust and moisture prior to application. For long-term outdoor exposure, assess additional UV or mechanical protection as required by the installation environment.
