Powermatic 4 inch splice fitting connects sections of 4 inch dust collection hose in a JET dust collector system, so runs can be extended or rerouted while keeping the same hose diameter through the line. The fitting is designed for use in dust collection applications, giving woodworking machinery a consistent 4 inch pathway for dust and chips to travel. Being part of the JET dust collectors family keeps this fitting aligned with common shop dust collection layouts. The fitting serves as a joiner between hose sections, so long straight runs or transitions around equipment can be built without changing hose size. In a machinery dust collection setup, this type of splice fitting helps maintain a continuous duct line where direction changes or layout decisions require multiple hose sections. That role keeps airflow moving toward the dust collector rather than leaking at joints.
The 4 inch diameter splice fitting is slightly undersized so it slips inside the dust collection hose, turning the joint into an internal connection that supports the hose end while maintaining the 4 inch flow path. Because it has a one degree tapered fit, the splice enters the hose more easily at the start and tightens as it advances, which helps seat the fitting securely along the hose without an abrupt bind. This tapered geometry gives the installer more control during assembly on long or awkward hose runs. In practice, the undersized, tapered design works together so each hose end grips the fitting along a length of contact, which helps hold alignment of the duct run between machines and the JET dust collector.
This 4 inch diameter splice fitting is described specifically for JET dust collectors, so it fits into dust collection layouts that are built around 4 inch hose connected to those machines. In that role it acts as a straight joiner, linking two hose sections wherever the run needs to be extended or repositioned around shop equipment. In a machinery dust collection setting, elbows are used whenever the ductwork changes direction, and this splice fitting complements those elbows by providing the straight connections before or after direction changes. The fitting is part of a dust collection system that moves material from woodworking machines to the collector, so keeping a continuous 4 inch path helps the system carry dust away from the work area.
The slightly undersized body of the splice fitting is engineered to fit inside the hose, so the hose wall can compress around the fitting and form a snug joint that resists gaps in the dust line. Its one degree tapered fit means the outer surface is not perfectly parallel, allowing the hose to tighten gradually along the fitting length as it is pushed farther in, which helps maintain joint integrity under normal dust collection airflow. All plastic fittings and hoses in the system must be grounded against static electrical build-up, so this splice fitting participates in the grounding strategy across the plastic components of the dust collector ductwork. In regular use, the combination of internal coupling, taper, and grounding requirement supports a dust collection run that stays connected and manages static while the JET dust collector operates.
The 4 inch diameter splice fitting is slightly undersized to fit inside 4 inch dust collection hose, so it joins hose sections that are built around a 4 inch duct line.
The one degree tapered fit lets the splice fitting enter the hose gradually, so it seats more easily and tightens along its length to support a firm dust collection joint.
The 4 inch diameter splice fitting is described for JET dust collectors, so it integrates into dust collection systems using JET machines and 4 inch hose runs.
The splice fitting is used between hose sections in a 4 inch dust collection run, so straight segments can be extended or redirected around machinery and elbows.
The splice fitting is a plastic fitting used in dust collection, and it works alongside plastic hoses that must be grounded against static electrical build-up.
All plastic fittings and hoses in the dust collection system must be grounded against static electrical build-up, so this splice fitting participates in that grounding approach.
The 4 inch diameter splice fitting with a one degree tapered fit is built to sit inside 4 inch hose and join sections in JET dust collectors, so it supports straightforward dust line layout changes. Its slightly undersized, tapered design helps create snug internal joints, which matters when tying multiple machines into a continuous 4 inch dust collection run. For shops using JET dust collectors and 4 inch hose, this Powermatic splice fitting aligns with the system dimensions and grounding needs so dust can move from tools to the collector through connected hose segments.
