Flashers Silicone Roof Jack For High Temp Applications

Flashers High Temp Roof Jack

Check Price on Amazon

Flashers #3 silicone round roof jack is designed for pipe OD ranging from 1/4″ to 5″. The unit is 100% made in the USA, reflecting a strong domestic manufacturing emphasis. The silicone construction supports a continuous temperature range from -100 to +450 degrees Fahrenheit, making it suitable for various environmental conditions and refrigerant line penetrations where heat exposure may occur. Proper measurement of the outside diameter is recommended to ensure a snug, leak-free installation.

Key considerations:

  • Material: Silicone offers excellent temperature resistance and flexibility for roof contours.
  • Temperature tolerance: Ranges from extremely cold to very hot, reducing the risk of cracking or gaps around penetrations.
  • Fitment: Verify OD before ordering to avoid incompatible flashing sizes.

VIVIDA #4 Silicone Roof Boot For Corrugated Roofs

VIVIDA Silicone Roof Boot

VIVIDA offers a #4 silicone metal roof boot with a square base designed to conform to metal corrugated roof profiles. This boot accommodates 2-3/4″ to 7″ OD pipes and includes screws and a hex socket for secure mounting. The flexible base can be molded to roof rib lines, providing a tight seal while minimizing the risk of water intrusion. Temperature tolerance is suitable for typical HVAC refrigerant line setups, with a safe operating window up to 446°F. Users should avoid overtightening screws to prevent damaged seals.

Key considerations:

  • Base design: Square base improves alignment with corrugated surfaces and reduces wobble.
  • Installation flexibility: Rubber boot can be cut to size for non-standard installations.
  • Temperature limits: High-temperature silicone rubber sustains performance within specified range.

Flashers Grey EPDM Roof Jack For Metal Roofs

Flashers #5 Grey EPDM round roof jack is designed for pipe OD ranges from 4-1/4″ to 7-1/2″. Like the other Flashers products, this unit is 100% made in the USA and emphasizes internal measurements to match the installation needs. The EPDM material provides reliable weather resistance and a suitable continuous temperature range for many refrigerant line penetrations. Projection clarity matters; ensure the boot diameter aligns with the pipe size before tightening screws.

Key considerations:

  • Material balance: EPDM offers durable weatherproofing with good elasticity.
  • Size compatibility: Suitable for larger pipe penetrations common in industrial HVAC setups.
  • Manufacturing origin: Domestic production supports quality control and supply chain reliability.

The SZRKRLA 29986 Plus II hose features a compact 1/4″ line with a built-in ball valve for precise refrigerant control. The 72″ length provides flexibility for accessing service ports on larger configurations. The design enables full-flow operation with standard gaskets and valve openers, and includes a metal handle at the hose end to facilitate sealing and capture of gas. This configuration supports one-handed operation in cramped spaces and is compatible with common R-410A refrigerants and other standard HVAC fluids.

Key considerations:

  • Valve design: Ball valve permits quick on/off control without disconnecting hoses.
  • Durability: Steel components and robust fittings enhance longevity under frequent use.
  • Compatibility: Suitable for a wide range of refrigerants with standard flare fittings.

Buying Guide: Roof Jacks And Refrigerant Line Accessories

Selection tips can help ensure a leak-free, durable installation when routing refrigerant lines through a roof. Consider the following perspectives and trade-offs:

  • Material and temperature tolerance: Silicone options offer excellent heat resistance, flexibility, and endurance in harsh weather; EPDM provides good sealing with strong UV resistance. Match the material to roof type and climate.
  • Base design and fit: Square bases on some models improve alignment on corrugated metal roofs, while round bases may be simpler for flat-surface installations. Ensure the OD range matches the pipe size and account for possible trimming.
  • Installation ease: Some products include screws, sockets, or built-in valves to simplify mounting and refrigerant handling. Consider whether you need a quick-connect capability or a more permanent seal.
  • Temperature ranges: Continuous operation temperatures are critical for reliability. Verify the operating window not only for environmental exposure but also for the refrigerant temperature during service.
  • Hose and tool compatibility: For charging hoses and diagnostic manifolds, verify fittings, flare sizes, and pressure ratings align with the system’s refrigerant type (R410A, R22, R404, etc.).
  • Durability and origin: Domestic-made products may offer tighter quality control and faster replacement availability in some markets.
  • Maintenance and safety: When using multiple components, ensure accessible labeling and clear shutoff controls to minimize accidental releases during service.

This selection emphasizes combinations of roof jacks and refrigerant-line accessories that balance fit, durability, and safety. Each product serves distinct roof types and pipe sizes, enabling installers to tailor choices to project requirements without compromising on leak prevention or thermal performance.
