EVIL ENERGY 3/4" Heater Hose 5FT (3/4" ID) EPDM Coolant Hose with 5 Clamps — 100 PSI, SAE 20R3

EVIL ENERGY 3/4" Heater Hose is a 5-foot EPDM coolant hose built to SAE 20R3 standards, rated for 100 psi working pressure and supplied with five stainless clamps for reliable radiator, heater, and overflow connections.

This heavy‑duty heater hose is designed for automotive cooling systems and hot‑water lines where a flexible, heat‑resistant connection is required. Constructed from EPDM rubber and manufactured to exceed SAE 20R3 Standard Wall Class D‑2 requirements, the hose balances durability, bendability, and temperature tolerance. It is sized to fit 3/4" (19 mm) inner diameter needs and arrives with five clamps so you can cut to length and secure fittings right away.

What are the key performance specs and limits of this hose?

The EVIL ENERGY heater hose offers clear operational limits so you can match it to your system. It supports continuous service across a broad temperature range and includes an industry‑standard burst margin for safety.

• Inner diameter: 3/4" (19 mm) with ±0.6 mm tolerance
• Outer diameter: 1.10" (28 mm) with ±0.8 mm tolerance
• Length: 5 feet, easily cut to custom lengths
• Working pressure: 100 psi; burst pressure: 300 psi
• Temperature range: -40°F to 257°F; minimum bending radius: 152 mm

How does the material choice affect durability and compatibility?

EPDM rubber was chosen for its resistance to heat, ozone, and common coolant chemistries, which gives the hose a long service life in typical vehicle and equipment environments. The compound resists hardening and cracking under repeated thermal cycles.

• EPDM resists coolant, water, and antifreeze exposure
• Withstands hot‑water and steam‑adjacent temperatures within the stated range
• Flexible enough to negotiate bends without kinking at specified radius
• Meets SAE 20R3 wall thickness requirements for reliability

In what applications will this hose work best?

This hose fits a variety of cooling and heater line uses in automotive and light‑equipment settings. It’s intended for connections where a 3/4" ID is required and where a reliable clamp connection is practical.

• Heater core inlet/outlet lines in cars and trucks
• Radiator to overflow or auxiliary reservoir connections
• Hot‑water heater plumbing on engines or stationary equipment (non‑pressurized where applicable)
• General coolant circulation lines that require EPDM compatibility

What does the kit include and how simple is installation?

The product ships as a ready‑to‑use 5‑foot hose with five clamps, so you can size and secure it on first installation without extra purchases. Standard hose clamps are provided to match common hose barb and pipe fittings.

• One 5 ft length of 3/4" ID EPDM heater hose
• Five metal clamps suitable for 3/4" connections
• Cut‑to‑length convenience for custom routing
• Compatible with standard screw‑type clamp tightening tools

Who is this for: EVIL ENERGY’s 3/4" 5FT heater hose is aimed at DIY mechanics, professional technicians, and equipment owners who need a durable, heat‑tolerant replacement or upgrade hose for cooling and heater circuits. Choose this hose when you require EPDM chemical resistance, a 100 psi working rating, and the flexibility to trim and clamp to a variety of fittings. It’s not intended for applications outside the listed temperature or pressure limits or for media not compatible with EPDM.
