حلقات O من Viton FKM | AS568-150 | داش 150 | صلابة 75 | أسود (40 / عبوة)

The high-temp rating on these Viton FKM o-rings is exactly what I needed for my hydraulic press rebuild. They seated perfectly in the gland without any binding, and the package of 40 gives me plenty of spares for future maintenance.

After dealing with constant leaks from standard Buna-N seals in my high-temp application, these Viton o-rings finally stopped the drip. The 75 durometer feels firm yet still seals nicely against the port, and I've had no issues up to 350°F so far.

These seals slipped into my hydraulic fittings perfectly and held pressure at 350°F without a hiccup. The 75 durometer hardness feels solid, and the package of 40 means I've got spares for the next rebuild.
