Antrys Z2000 Oil Burner Setting Gauge

The Antrys Z2000 gauge is designed for Beckett models including AF, AFG, SR, SF, and AFII, and other burners using F-style or FB-style heads. It helps you accurately set the nozzle-retention head distance and adjust the electrode angle without removing the burner from the heating equipment. This tool targets common issues such as failed ignitions and black smoke by promoting optimal combustion through precise adjustments.
TOMLEND Z2000U Gauge Kit for Beckett

TOMLEND’s Z2000U gauge kit is built to adjust the correct distance between the nozzle and the retention head and to set the electrode angle within the burner tube. It lists compatibility with Beckett AF, AFG, SR, SF burners with F-heads and AF II burners with FB heads, as well as other manufacturer-recommended nozzles. The design aims to restore factory settings without disassembly, simplifying maintenance and ongoing calibration for consistent performance.
Giokyi Oil Burner Electrodes Setting Gauge

Giokyi’s gauge emphasizes durable construction and stability, designed to adjust the nozzle-to-retention head distance and electrode angle without removing the burner. The tool is described as corrosion-resistant and long-lasting, with clear orientation cues: place the gauge on the nozzle opening facing up, use the top bump to adjust angle, and use the front protrusion to set the distance. It supports Beckett AFG and AF II, SF, SR models, among others, offering a practical option for technicians maintaining oil burners.
MorningRo Solid Spray Nozzle 2 Pack

MorningRo provides two solid spray nozzles with an 80-degree spray pattern and 0.85 GHP. Crafted from heavy solid brass, these nozzles offer durability and resistance to corrosion, and brass’s excellent heat conductivity helps dissipate heat away from the nozzle surface. This design supports reduced varnish and oil buildup, promoting longer service life and reliable ignition across various burner applications.
Delavan 1.25gph-80 Hollow Spray Nozzle

Delavan’s hollow spray nozzle delivers 1.25 gallons per hour at an 80-degree pattern. The nozzle’s hollow cone design supports a reliable spray distribution, which is a key factor in achieving uniform combustion and reducing ignition struggles in larger or high-demand burners. It provides a balance between flow rate and spray geometry for compatible oil burner setups.
Buying Guide: Key Purchase Considerations
- Compatibility: Verify burner model compatibility (Beckett AF, AFG, SR, SF, AFII, and head types F or FB). Some gauges specify only certain combinations; confirm before purchase.
- Purpose: Decide whether you need a gauge for precise electrode angle adjustment, nozzle-to-head distance, or both. Gauges can simplify calibration and maintenance without full disassembly.
- Durability: Look for corrosion-resistant materials (brass, stainless steel) and robust construction, especially for gauges used in heating equipment exposed to heat and fuel.
- Ease of use: Tools that mount on the nozzle, with clear orientation cues and intuitive adjustments, save time during servicing and reduce error.
- Reuse and maintenance: Some gauges facilitate restoring factory settings; others provide precise angle adjustments for ongoing optimization. Consider long-term maintenance needs.
- Spray nozzle selection: For nozzles, consider spray angle (e.g., 80 degrees), material (solid brass vs hollow), and flow rate compatibility with your boiler or furnace to ensure efficient combustion.
- Ignition reliability: Tools that address common issues like hard starts, smoke, or varnish buildup can improve overall efficiency and reduce fuel consumption when used correctly.
- Cost vs value: While gauges and nozzles are generally affordable, evaluating how often you service or replace components helps determine the best overall value.
The options above represent practical tools for improving oil burner performance. When selecting a nozzle or gauge kit, prioritize model compatibility with your specific Beckett or similar burner, and consider how each tool can contribute to easier maintenance, more consistent combustion, and reduced fuel waste over time.
